Got the AR-pistol bug recently and I ran across this video on Youtube of a beltfed .22 upper. Not something I'm considering seriously but it sure looks like fun!
Anyway, I tried some quick Google-fu and some vague answers popped up saying that belt-fed is fine as long as the belts are only 10 round groups. Any truth to that?
