I have the RRA Entry tactical AR15. I enjoy the range time i get with it. We are all aware of the ammo situation. I am looking into Conversion kits with .22Lr. From experience, does anyone have some suggestions. I am aware of that .22 is not the strongest caliber, I am just seeking some more recreational time with it at a cost effective rate. I am currently interested in the CMMG kit with the full size AR type mags. Any critical advice in terms of reliability, cost, durability? thanks
