The M4-22 PRO is a premium .22 caliber semi-automatic tactical rimfire rifle with aluminum upper and lower receivers and all the features of a true M4. The M4-22 PRO is largely mil-spec compatible and will accept most AR15 stocks, handguards and sights. The M4-22 has the look, feel and controls of a true M4 and is a perfect platform for training applications or backyard plinking.
Shot 300-400 rounds with no issues after initial clean. Crisp trigger. Magazines have a unique steel guide that will increase their durability. I can recommend it to anyone one that has an eye out for an AR type 22LR. I had the Smith & Wesson variant. The stock wiggled too much. Finish was poor. Had a few FTFS. Sold it. I would rate it at the bottom of the ladder. The Tippman looks like an AR-15. My Walther variant looks like a toy even though it shoots pretty good. I rate it number three on my list. My number two is the HK variant. Make sure you clean it often. Rimfire ammo tends to be much dirtier than centerfire.
