I am admittedly a complete rookie when it comes to not only ARs, but semi autos altogether. Tomorrow I have the opportunity to pick up a Ruger SR-762 in a trade, according to MSRPs and such i've managed to get a pretty good deal on it from my end. I saw they were discontinued, does anyone ere have experience with these rifles? Might this finally be the semi auto rifle i actually keep? I would only be into it for about $1,000.
