1) The gun wasn't designed to prevent slamfires. (The SKS has similar problems but it's a MUCH older design, the US military knew about the problem and didn't try to fix it)
Actually, I think this is incorrect. The M-14 benefitted from the
wisdom gained on the M1 Garand, an even older design than the SKS. They simply lightened the firing pin, as well as the other mods posters pointed out. So they did fix it (relatively), just earlier in the lineage. Mr. Stoner
apparently never got the memo, and relearned the whole slamfire issue again.
2) The gun wasn't designed to contain slamfires to a closed bolt position. (Potentially fatal to shooter)
There are in battery slamfires and out-of-battery slamfires. Isn't this just the definition of those two types? The out-of-battery type are dangerous on any rifle, and as far as I can tell are due to one of four causes:
- Commercial "sensitive" primers rather than military style primers (I have read that this is an issue potentially independent of the firing pin)
- stuck firing pin on a free-floating design (cleaning/lube issue)
- primer set too high
- excessive parts wear (safety bridge, pin, etc.)
I would even speculate that an unlucky chunk of debris could cause an out of battery slamfire on any semiauto.
He doesn't state that the M14/ M1A wasn't designed to prevent slamfires, he repeatedly states that the ONLY WAY TO PREVENT THEM IS WITH HARD BELOW FLUSH PRIMERS. So the only "designed" aspect to prevent slamfires is not intrinsic to the rifles design.
As I understand it, the hard primer is to counteract the free-floating firing pin design. An above-flush primer would seem to be an issue on any large caliber semi-auto because it's the bolt slamming forward on the primer.
For crying out loud theres a guy making firing pins for SKS's that prevent this condition and he's only charging $3.00 for them!
It sounds very simple, but I think there are design tradeoffs. The
SKS was originally designed with a firing pin spring to prevent slamfires, but they took it out! Colt tried a firing pin spring on the M-16 to resolve slamfires, but opted for a lighter pin design instead. Why? probably reliability. You can go titanium, but
there are problems there as well. Go any lighter and you may end up with broken pins. I'm sure it was a tradeoff of some very low risk of slamfire vs. reliability. It is a combat rifle at heart after all.
3) The gas system is not adjustable to accomodate different powder charges and bullet weights. (batters the gun to death with commercial ammo)
This seems to have been dealt with in other comments.
4) The bedding material is only rated to last for 1000 rounds maximum. (1 year for average match shooter). I'm still amazed that several posts claim that bedding that degrades from solvent contact is OK when we've had JB Weld since 1968. If bedding is only an accuracy/ match grade thing, it would seem screamingly obvious to me that making the bedding out of something thats solvent resistant is a good idea.
I am not aware that any manufacturer actually does a bedding job on the rifle - is that not between you and your gunsmith or your rifle builder? There are many different ways to bed the M1A that I have seen, some probably better than others. You can even
do it yourself and use any material you like.
5) The barrel must be cleaned from the muzzle. (Much harder than it needs to be)
This doesn't seem too out of line for a semiauto. As someone pointed out, there are alternatives, like boresnakes that allow you to clean the other way if you wish. Probably the most important thing is to clean it upside down because of the gas system, which doesn't make it any easier.
6) Bore solvents supposedly deteriorate the bedding. (Seriously stupid)
Again, as someone said, this is only if you choose to bed it in a wood or fiberglass stock. If you choose the evil SAGE chassis, it's not an issue, because it is instantly bedded. Frankly, I think any wood or fiberglass rifle you choose to bed would suffer this problem. It's a wood stock problem, not an M1A problem.
7) The ejection system batters brass so hard that reloads aren't realistic. (Annoying but common enough among all military semiauto rifles)
As beaten to death, I don't think this rifle was ever intended for reloads, and I'm not sure it is any harder on the brass than other .30 cal semiautos.
8) One MOA is considered the pinnacle of accuracy from this platform. (Depressing considering the folklore about how amazing it is)
Sub-MOA and semiauto battle rifles just aren't something that goes together as far as I can tell. As I am learning, sub-MOA is important to snipers, but not "riflemen." The MOA standard for riflemen is 4 MOA,
based on what I've read. I think the M1A is considered more a rifleman's rifle than a sniper. As I understand it, the more you accurize a rifle, the more finnicky it gets (except going with a bolt action). That said, I'm not sure there are semiautos out there that significantly exceed the accuracy of the M1A, and many that do much worse.
9) Well bedded rifles require a hammer and a brass drift punch to field strip. (Again, annoying but "match" stuff is generally a PITA to disassemble)
Bedding is tight for a reason.
10) 211+ quality assurance testing fixtures, 400+ manufacturing steps, all based on M1 fixtures and jigs, to produce a rifle design that was/is flawed from the beginning.
It's not perfect for sure, and it's from a different era and philosophy of design for sure, but it does seem to do the job after all these years.
The one thing that always amazed me about the M14 is, it was one, if not the shortest lived and issued rifle our military used, but somehow its the greatest, and people seem willing to argue on endlessly in its defense. The despised M16 series and all its variations is now I believe, the longest lived.
This is one statement I don't get. If I'm not mistaken, the M-14 has been continuously issued in one form or another since it was originally built. Granted, except for 1960-67 or so, it has always been for special purposes, but it has been issued nonetheless. The Army is even issuing them again from what I understand. So, in actuality, it is the oldest continuously issued design.
