I've started looking at Tacticool .22's recently. Most of them appear to be polymer based. I know it's cheaper to build them that way. I just don't like em. I've seen the higher end conversion kits from Tac Solutions. They are nice, but $500 to $600 seems high. You can buy a Colt which appears to be the best built for around $400. So. Buy a higher end dedicated .22 upper conversion kit, or a full rifle?
