I have a Armalite AR-10 and like most, but not all AR-10's it has an A2 style butt-stock and a few 7.62 AR's have a adjustable butt-stock like most of the AR 5.56 platforms have. I presumed that the A2 stock handled recoil better, but I don't know that to be factual. The A2 fits me fine, but the Warden hefted it to her shoulder and I thought it to be a little long for her. She can adjust her AR-15 stock to fit. I believe I will leave the AR-10 the way I got it, but does anyone have any actual experience using both style stocks on a 7.62 platform. Would you change out the stock if it were yours?
