I have always wanted a Match grade M1A, and will some day. But through the years I've managed to acquire a AZEX/IMBEL 50.00 FAL with an 18" barrel and a SIG Sauer 716 Patrol.
The Fal just seems to feel more satisfying in hand. It is accurate enough, 2-2.5" groups(Leupold Vari-X III 1.5x5), but to be fair I have never really worked up a serious accuracy load for it.
The SIG is 1 1/2 lbs. lighter and is capable 1 moa (Vortex PST 1-4x) now that I have put in a better trigger.
It would be hard to choose one over the other but it would be more practical to grab the Sig for serious business.
