The M4-22 RedLine is a joint collaboration between Tippmann Arms and Tandemkross with a goal to offer the M4-22 in a competition ready configuration. The M4-22 REDLINE features the TK "Game Changer PRO" Compensator; TK AR15 "hiveGrips"; 16" red Fluted barrel, and aluminum receiver w/red accents. The M4-22 RedLine is largely Mil-Spec compatible and will accept most AR15 stocks, handguards, and sights. The M4-22 REDLINE has the look, feel and controls of a true M4.
