The M1A is not as easy to maintain as the AR-10. The AR 10 also shares many of its parts with the AR-15, making those parts much easier to replace should the need arise.

The M1A is also longer. The AR-10 has a choice of barrels that run from 16" to 24". The AR-10 is the handier weapon. Twenty Five round mags can be had for the AR-10.

FWIW, I have lots of long range trigger time with the AR-10,M1A,FAL and even the SR-25.When it hits the fan I'd go with the AR-10 or the SR-25 every time.

Most M1A's need to be tinkered with to make them excellent shooters. I have shot several high dollar match guns that very accurate, but they had premium barrels and action jobs.

I have yet to pickup an AR-10,SR-25 or even a DPMS.308 that was not fairly accurate when mated with a good scope.
