Why not .223?
My choice for a 22LR would be the GSG-5. And for the AR platform... the DPMS LR-308 hell of a gun.
well, im only 17 and .223 is just to expensive for me to shoot...
and I dont know why I like the sig so much, I was at gander mountain the other day, and was feeling out all of the other .22's and it just feels the best to me...
it's going to be ether the sig, or the smith and wesson M&P 15-22. that is a nice gun also...
