my friend is looking for a .22 rifle.
he has narrowed it down to two rifles (SO FAR)
the gsg-5 (mp5 type .22) and the M&P 15-22 (AR variant in .22)
he says he's really leaning towards the M&P 15-22 but wants to make sure of everything. so that's where you guys come in.

are these pretty good choices for a guy who's shot plenty of calibers and plenty of firearms? and are there even better rifles than these that you can get in the U.S.?

he doesnt have a budget that i know of. but lets try to keep it reasonable.
he's looking for the one's eh...around 500-600 dollars. maybe less. maybe more.

your turn.
