My father, Clint Fowler, is a well known National Rifle Match shooter and gunsmith of the M1/M1a/AR15 match rifles. His name is thrown around in many of the shooting forums.

In 2008 I built him a site at m1-m1a-ar15.com. I then helped him get an ebook on M1 accuracy jobs done. He’’s well respected in this area of expertise.

Unfortunately, the first person who built a site on that domain for him was a “friend” of his who really just wanted to associate his name with my father’’s for the traffic and recognition. I took the site over and rebuilt it and got rid of that squatter. But … he is the one that had registered the domain name and he never turned it over to me. He let it expire. I did my best to try to get it back, but someone purchased it to capitalize off my Dad’’s traffic. He even checked Google cache and structured his site exactly as my father’’s site was structured. What an ass.

So …I purchased gunsmithing.co and rebuilt the site on it to replace m1-m1a-ar15.com. I also built him a blog with his exact name at clintfowlerrifles.com. But when I went to Google and typed in my father’’s name, the original domain was in first place. The squatter was ranking #1 in Google for my father’’s name.

I did a bit of SEO for the new site and that was enough to get my Dad’’s new site on the first page of Google for his own name and for m1-m1a-ar15.com, and along with that, his traffic is back at full speed.

So, officially, m1-m1a-ar15.com - Clint Fowler Rifles has moved to gunsmithing.co

The group on the left was shot first. The elevation dispersion of that group told me the gas system needed more volume. I adjusted the set screws inside the gas plug outward 1 ½ turns and shot group 2. It is .910” wide and about 1/2” tall. The horizontal dispersion of group 2 told me my first adjustment was a little too much so I moved the set screws back in by about 1 hour of turn. That will cut the width slightly. You can tell I have tested a few guns cant you?

The Clint Fowler Accuracy Job

This M1A was a complete rack grade M1A with a Winchester G.I. chrome lined barrel. I did my standard accuracy job (no lugs) and tested it on my machine rest @ 100 yards. I used my standard test load of 40 grains of 1MR 4064, Remington Case, Fed. 210M primer and 168 Gr. Sierra bullet. I usually get 3/4″ to 5/8″ groups but this one was under 1/2″. A dime completely covered it. All this with a U.S. G.I. chrome lined barrel made by Winchester. This is why I never evaluate barrel quality until after the accuracy job is done.

After spending 10 years building double lugged M-14/M1A’’s practically all of which shot 1 MOA or less, I decided to take another look at the M-1 to see if the things which worked well on that gun also would work on the M-1. The first innovation was to put a lug on the rear of the receiver so it could be bolted down. Without a doubt this was successful. It relieved the trigger guard of its job of holding the gun together and greatly enhanced the life of the bedding job. Later, I added the front lugs to finish the job. There are two front lugs both small and mounted on the right and left sides of the receiver just under the front corners of the trigger plate. The action is pillar bedded with great care. Custom barrels were installed, op-rods aligned properly, and gas cylinders were also fitted properly. I expected dramatic results when I tested the first one but I was disappointed. Many of the guns did shoot under 1 MOA, but many did not which was very frustrating. The problem went into my hair-top computer and weeks later the analysis came out. The gun actually had two problems, both of which must be addressed in order to obtain peak accuracy and also to retain it. The first was that long skinny op-rod. I knew how to straighten and align them but I didn”t know how to prevent them from bending later. Accuracy procedures up to then said that the op-rod should touch nothing in its cycle so metal was cleared away in the stock ferrule, the liners were removed from the hand guard all in an effort to give the op-rod unfettered room to move but also unfettered room to bend. Clearly we needed some op-guide system like the M-14 has but how to put one on a rod with two bends in it? Further work for the hair-top computer. The solution came one day when I was examining a DCM issue M-1 and noticed a .050 gap between the bottom of the op-rod and the ferrule. Why the gap? Well Dummy, it’’s a combat gun and you need such gaps so the gun will function even if cruded up with mud or sand and stuff like that. Hmm. None of my shooters use these M-1′’s as combat guns so why do I
need poorly fitted parts? I wonder what would happen if we went in just the opposite direction? Instead of loose fitting combat parts we have snug fitting match parts, but again, how to do it on an op-rod with two bends in it. Then came the solution. The guide system had to be two pieces. The forward piece a circular track epoxyed in the upper hand guard and a lower track silver soldered in the stock ferrule. Both had to be fitted just right. They could not bind the op-rod, but they had to almost touch it, a light slide fit. I built the first pair and installed it in my own M-1 hoping it would still function without binding. I loaded a clip of Israeli ball and shot it into a rotten tree stump in my yard. It worked and thus a serious durability problem on the M-1 was solved. That still left the second problem.

I became aware of it after building a rear lugged M-1 with a Krieger barrel for a customer in Washington State. On the test bench it shot 2¼ inches. For a Krieger barrel this was not acceptable so I set the gun aside with a feeling of frustration. I knew the gun had been built with care. I knew the barrel was first class. It had to be something else. A week later the hair-top computer spun out the answer. It was timing. The bullet was still caught in the rifling when the op-rod started to move rearward. It set up barrel vibrations, which affected accuracy. This explained all those guns with good components, which did not shoot well. They could all have been made to shoot good if a way had been found to delay the op-rod function until the bullet just cleared the muzzle. The problem dictated the solution. When the bullet cleared the gas port a high-pressure impulse of gas filled the chamber between the plug and piston tip. If the volume of this space was just right the gun shot good, if not, it shot poorly. Perhaps we could do something to make the volume variable. The solution was an adjustable gas plug. A plug with a threaded bore with two setscrews mounted inside. By adjusting them outward the volume was increased. More volume, more time needed to fill it. Time measured in parts of a millisecond. To say this solution worked is an understatement. It was the missing link, the last rear hurdle. Back to that gun for Washington State. I pulled the plug on it took dimensions off it and made a crude drawing. On my lathe I made my first one that afternoon. Next morning, out to the test bench, first group 2¼ inch, which is what I expected. First adjustment, outward ½ turn, group shrunk to 2 in. On the fifth ½ turn adjustment; the group was .800 in. I sent all five groups to my customer and explained what I had done. To this day, I”ve never heard a word from him but then,
us gunsmiths rarely ever hear from customers unless something is wrong, so I wasn”t surprised. I”ve learned no news is good news.

With these innovations the average accuracy levels came below 1 MOA. It was only an occasional gun, which didn”t make it, and this was usually traceable to poor barrels. Recent work with fire lapping has made some GI barrels and Douglas barrels shoot like Kreiger barrels. I”m really pleased with this as it cuts barrel cost dramatically. All this caused my reputation on the M-1 to soar to such a point that a military armorer said “If you want a good shooting M-1 get Clint Fowler to build it.” Getting such praise from a military armorer is rare. Those guys are convinced that service rifles are their art form for a civilian gunsmith to be recognized is rare.

The most cost effective gun I build is a DCM M-1 with new GI barrel, a rear lug and pillar bedding, with op-rod tracks and adj. Gas plug and maybe fire lapping. It can be expected to shoot 1 inch or less at 100 yards with good ammo. All provided at a total cost under $500.00.

1. Make sure all locking surfaces are square with the bore axis.
2. Make sure the barrel is mounted square. There is a trick to this.
3. Install a free float tube and get the sling swivel off the barrel.
4. Install the front sight squarely and vertical so that the rear sight is on center.
5. It is very critical that the barrel collar be absolutely square with the bore. This is not always true on factory guns. That is why I like to turn my own barrels or install Krieger barrels.
6. Test the gun. If accuracy is over 1 MOA try fire-lapping the barrel. It’’s worked for me several times. This gun can be made to shoot near ½ MOA very consistently with good barrels.
7. Good handloading practices are the final element. The better the ammo, the better the groups.

To a Highpower Rifle Shooter his accuracy demands are less stringent. He shoots at a target at 600 and 1000 yards in which the smallest ring at the center; the X-ring is exactly 1 MOA in diameter. He wants a rifle that will deliver all its shots into that circle. Taking his own errors of sighting and trigger control into account, he needs a rifle that will shoot 2″ to 3″ groups at 600 yards. I can assure you that most Model 70 Winchesters and Remington 700′’s plus the M-1 Garand, the M-14/M1A and the AR-15 can be tuned to such a point that capable shooters could shoot 200 possible scores at 600 yards with them. I personally have shot several 200′’s at 600 yards with a Model 70 Winchester in cal. 308 and have seen M1A’’s do it also. The AR-15 in recent years has also done it too. The M-1 Garand, to my knowledge has not done it but only because we have only recently found out why it had accuracy problems and how to cure them. Accuracy levels any less than 1 MOA are acceptable.

First lets examine the M-14 or M1A. There are things I do to this gun that are producing the accuracy levels needed for today’’s Master Class and High-Master Class Shooters. I install both front and rear lugs on this gun. Both lugs are of my own design, a design that was copied by Armscorp and by Smith Enterprises. They say that imitation is the sincerest form of flattery. Of the two lugs, many say the rear lug is the most important, but I disagree. Why? Because if you examine the forces placed on the receiver by the act of firing one round you will see that the front of the receiver tries to rise upward. The thrust on the rear of the receiver is downward because the receiver is held in the middle by the hooks on the trigger group. This being the case it’’s easy to see that rear lugs only increase bedding area while front lugs do all the work of holding the receiver securely in the bedding job. This also explains why guns properly double lugged will wear out a barrel and sometimes more before a new bedding job is needed. Contrast this to an unlugged gun that will wear out a bedding job in 1200-1500 rounds. In my bedding jobs I use steel bushings around both bolts. The surest way to ruin a bedding job is to tighten the bolts too tight. My steel bushings prevent that and also preclude the use of torque wrenches to tighten the bolts. The technology worked great on bolt guns so I saw no reason it wouldn”t work well on service rifles. It did.

Another thing I do is free float the barrel, another advantage of a front lugged gun. Free floating produces slightly better accuracy but the real advantage to you will be in stability of zeros. The lack of forend contact means that sling tension cannot now influence group location at 300 yards rapid fire so that you can now place two groups in the center, one on top of the other. This is not easily done with a gun using forend contact. The other thing I do to the M-14 is to see that the op-rod guide, the flash suppressor and the gas cylinder are all properly fitted and once they are properly fitted they are loc-tited into position. My trigger work is basically as others do them except I am extra careful to make sure that both sear hooks contact the sear. This produces a trigger that lasts longer and is more uniform in pull. The rear sight is another place I examine closely. First I found that in 30-35 years of using the N.M. sight no one found a way to remove the backlash from the windage knob threads. I found a way to install a spring in the sight base, which bears against the right ear of the receiver and solves this problem. I call it my anti-backlash spring and it is included in all my N.M sight conversions. The sight conversion itself consists of re-threading the windage knob and sight base from 32 to 64 threads per inch, thus converting the G.I. sight to N.M. It checks out better on a dial indicator than an original N.M sight. Your choice of hooded N.M. aperture is included with this sight. Most of my customers choose one of two stocks, either the Bishop Heavy (Frank Smith) pattern or the MacMillan Fiberglass Stock. You will be well served by either one. Don”t choose the fiberglass stock thinking you will get some advantage over wood. The advantage is only theoretical. Today’’s wood finishes, mine included, are like encasing the wood in a plastic coating. I truly believe you could store one of my wood stocked guns in a 50 gallon water drum overnight and have no zero change or any sign of damage. I use a urethane clear coat finish that utilizes a catalytic hardener. It takes 3 days to finish but it looks like a Weatherby when done and is very durable.

If you are willing to do things as I recommend, I will guarantee accuracy of 1 MOA or less. To get this guarantee all you need do is buy my double lug accuracy job and a Krieger barrel. Using this combination, in the last year, my best gun shot .400, my worst shot 1.020. That’’s why I have no qualms about guaranteeing this combination.

Now we get to the M-1 Garand, a gun I love. I consider it to be the best-looking service rifle ever made and always thought I would make it shoot as good as the M-14. In the Beginning, I could not get those accuracy levels except occasionally, but that’’s not good enough. I wanted to be able to promise those levels consistently. It took some doing. First you”ve got to understand that in 1964 the M-14 came on line and the M-1 was basically dropped like a hot potato. Everyone was sure that the M-14 with its short stiff op-rod was inherently more accurate and the 308 was inherently more accurate than the 30-06. They couldn”t wait to put their M-1′’s on the shelf. No one seemed to notice that the accuracy technology for both the bolt gun and the M-1 was in its infancy. For one thing, glass-bedding materials were new; having become available only shortly before the M-14 came out. Another thing was barrel quality. At that time there was only Hart as a custom barrel maker and Douglas as a production barrel maker. I can tell you I never saw either the M-1 or the M-14 with anything other than a G.I. barrel, or, later on, a Douglas barrel. Even bolt gun shooters used Douglas barrels. I don”t mean to imply that Douglas barrels are poor barrels, but even he admits they are not custom match barrels, though some of his barrels will shoot with the best customs.

I won my first 3 legs on Distinguished with an M-1 Garand 30-06 that would not hold the black at 600 yards on the old “B” target. Then, the Maryland State Team issued me a N.M. M-14. I went Distinguished in 1964 with that gun and averaged 100-16v at 600 yards with it. It was my first good gun. Since then I have shot 14 National records, about 1/2 individual and the rest team. I”ve won 4 Nathan Hale Trophies at Camp Perry and 5 Elihu Root Medals plus 2 regional and 12 state championships. All in all a very active and rewarding shooting career. In the latter half of the 1970’s I noticed that the Marine Corps Rifle Team was using a double lugged gun and their armorers showed me their system. I liked it and was impressed with the results they were getting with it. I did notice that their system required a modification to the op-rod in order to disassemble and I decided to see if I could change the design to avoid that if possible. The solution popped into my head while driving home from work one evening and as soon as I got home I made up two front lugs of my new design. I took them and 2 receivers I owned to a welder and had them welded on. That was the act, which snowballed into my current business. In the early 80’s I showed my guns at Camp Perry on Commercial Row and have been in business ever since.

During the 80’s and early 90’s the M1A was my bread and butter. I never had a lot of M-1 work, but I never lost my interest in the gun and started trying out on the m-1 some things which had worded good on the m-14, such as lugs. First came a rear lug, which was a definite improvement, but a thought was in my mind about some way of tying down the front of the M-1. I eventually figured out a way to do it and by God it worked! I still wasn’t satisfied because I knew in my heart that I still didn’t know the proper way to align the M-1 op-rod. One day I had six M-1 barreled actions on my workbench, and I knew that my reputation depended on how these guns turned out. Some of these guns had Hart barrels on them. Their owners were serious enough about accuracy to go first class all the way. I was sitting there sliding that op-rod back and forth and searching for a clue. It was 10 a.m. At 2 p.m. still sliding and searching I noticed a feature I had not noticed before. It was the secret for which I had been searching. I aligned all six of those M-1s the same new way and all were below 1 MOA except one, which was 1.2 MOA. I got telephone calls from those customers expressing their satisfaction with those guns. I had finally solved most all of the accuracy problems inherent in the M-1 and I could now tell my customers that consistent sub-minute guns could be had in the M-1 Garand.

My Garand business increased but I still did 3 M-14’s to every M-1. I still wasn’t satisfied because I knew that even though the op-rod left my shop in proper alignment the darn thing had a history of getting mis-aligned in use so there was one final hurdle to jump. I put my mind to it and at first the problem seemed unsolvable. How are you going to make an op-rod guide for an op-rod that is basically bent in two places? So the problem went into my hair-topped computer and there it stayed. Funny thing about those hair-topped computers … they work 24 hours a day, and about a week or two later the solution popped out. I theorized that since the op-rod had two bends they would each work like hinges. The front bend would bend upward when force was exerted on the piston tip and the rear bend would bend downward. Knowing this I assumed the guide should allow the op-rod to move upward only .005 inch before it was captured by a U-shaped channel embedded in the upper hand guard. The rear bend of the op-rod would be captured in a similar channel bedded in the stock’s forend. Thus the op-rod would not be allowed to bend more than .005 either place and thus it would slide rearward constrained by the channels and could not bend out of alignment. On the first gun I tried it on I only wanted it to work. I hoped that there would be no binding effect and there wasn’t. No increase or decrease in accuracy was observed, but I didn’t expect any. All I really wanted was the gun durability and maintenance of accuracy that the system promised. It was also a successful innovation. I can now promise an M-1 Garand that will shoot one MOA or better and will maintain its accuracy for the normal life of the barrel without op-rod problems. The truth is that my methods are a whole new technology on this gun and I figured it all out myself. No other gunsmith builds the M-1 the way I do. I suspect they will copy my methods, let’s see if they can get the same results that I do. My front lugs for the M-1 are located one on each side with the bolt heads hidden under the front corners of the trigger plate. The location of these bolts weakens a G.I. stock though some G.I. stocks are heavy enough to handle it. I like the Match stock for that and other reasons.

The final factor in the accuracy equation is the gas system. When functioning properly, the system allows the bullet to just clear the end of the barrel before the op-rod starts to function. Accuracy is best then because op-rod function induces vibrations in the barrel, which are harmful to accuracy. Some guns, however, start to function before the bullet leaves the barrel. These guns seldom shoot under 2 MOA regardless of barrel quality. Obviously, it would be desirable to be able to manipulate the gas system to accomplish the timing you desire so this was the area in which I directed my attention. I theorized that if we replaced the original gas plus with one that is adjustable for volume, we could accomplish that goal. I was right. I made a plug with a hole drilled through it and threaded. I then installed two short, flat-faced set screws. The outermost set screw is used to lock the innermost into position after it has been adjusted to optimum setting. I have seen guns go from +2 MOA to sub 1 MOA just by adjusting the volume outward by 2 full turns of the screws. The plug and the op-rod guides are included in the front end package mentioned in my price list.

I rarely get a gun back to rework something because I take pains to do it right the first time. I do stand behind them 100%. With Congress getting nasty about “assault rifles”, I think the M-1 is going to become more and more popular, so a really accurate M-1 is going to be a highly prized gun. If accuracy, durability, and dependability are what you are looking for, give me a call.
