    I have an AR10 now with components to build another with a longer barrel.

    The M1A is interesting to me, if you had to have just one which one would it be & why?
    The M1A is capable, reliable and can be exeptionally accurate, and certainly cool. But I'll tell you (owned both) you'll spend 2x+ to get that M1A to shoot as accurately as an AR platform.

    Here's one of what I have found with the new Springfield Armory M1A parts back in the 80's and 90's.

    The bolt roller has worn off in a few hundred rounds.View attachment 371741
    You are showing worn parts produced because I was...what is even the point. The SA parts now aren't even in the same league anymore. You act like the world/discipline of engineering/material science stood still since Reagan left office. I don't know why you took such offense to something I said. I'm sorry, please let it go. I swear I love M1As as much as you do.

    Why do you think I'm offended?

    AR platform, better ergonomics, better mounting capabilities, easier for barrel and accessories changes. I do love the old school M1A looks, but the win goes to the AR.

    My personal sample size is small. One M1A and two AR-10’s. The M1 wins hands down in reliability, for me at least. The AR10 wins for accuracy. An armalite and a S&W M&P 10 btw. If I had to have only one, I would personally go with the M1A. Just my small sample size experience.

    I watched a video by Reid Henrichs who runs classes. He said he never has an AR10 run his class without issues. Now that was quite a few years ago, so maybe the platform has been improved. I went with M1A over AR10. One is a Loaded set up as a DMR with a 3-12 on a Sadlak mount and a Socom with a CQB stock and Primary Arms 1x Prism red dot on this mount. Very versatile platform.

    When I first got my M1-A it would shoot 3-1/2" to 4" groups at 100 yds.
    So after careful examination I decided to glass bed the stock to the receiver.

    I first adjusted the steel liner to fit the receiver then filled the voids in the receiver with modeling clay so I wouldn't forever glue them together and waxed the receiver real good with paste wax as a release agent.

    Then I carefully applied the stock bedding compound to the stock and the receiver, being careful to center the barrel in the forend. Then I locked them together with the trigger group and let it set for a day.

    I then unlocked the trigger group and removed it, then took a rubber mallet and carefully smacked the butt stock and it popped right out leaving a perfect fit.
    I cleaned everything up and assembled the parts and went shooting.

    I am now able to consistently maintain 5/8ths inch center to center groups at 100 yds. and hit steel Rams at 600 yds with boring consistency.

    Was it worth it? ......Hell yes it was.

    I bought a M1a Super match years ago. They shoot extremely well and I like shooting it. Long term with such a weapon depends on a really good specialty gunsmith to keep it rebarreled. Proper stock bedding is mandatory for top accuracy.

    I have no experience with the AR10. The AR15 with very little effort is a really accurate platform. You can shade tree a box of cheap parts with nothing but a big set of channel locks and a 1/16th inch nail to drive pins, and it will operate. If the AR 10 is as easy to maintain and replace barrels as the AR 15, the long term for high volume shooting would be the AR10.

    That said, I still love the M14 chassis.
