I wanted a cheaper way to shoot drills with my AR-15. I spent the money and purchased a CMMG 22LR conversion kit with 3 magazines. I took it out to day, sighted it in and ran some drills. I put about 200 rounds through it today. All I can say is, why did I wait so long to get one. I didn't have any problems, all rounds fired. I sighted in for 25 yards and shot a few 1 inch groups. I then ran some basic drills on steel at 10 to 25 yards. There is just about zero recoil, but it's all the same controls and manipulations. I think I'm going to get a few more magazines and give this set up a try at steel challenge.
