MERRY CHRISMAS, EVERYONE! I'm thinking of buying an AR-10 or variant in 7.62 NATO after the holidays, and was wondering if anyone would mind giving some suggestions. I have a little experience with AR-15s, but virtually none with the AR-10s. Accuracy is a must and so is the availability of magazines (apparently different manufacturers use various magazine designs, unlike the AR-15s). It would be great if I could find one that uses M-14 mags, since I have several of them already on hand. I understand that some use FN-FAL mags, and some use their own designed mags. I plan on installing a scope and use the rifle primarily for target shooting and, of course, self-defense. Any and all advice is appreciated.
