i love rugers...i own 3...but that sr22 is just ugly!!!! and i think it costs more that either the colt m4 or the smith and wesson m&p 15
of those two, now that the smith has the threaded flash hider i like it better than the colt, the smith has the working bolt hold open, plus ive seen a colt/umarex that has a cracked lower (he said he dropped it from about waist high) its not even a crack but more of a CRACK (its bent at a 15 degree angle) but umarex is replacing it free
