This unit ships with a complete ZEROED parts package including ambidextrous charging handle, safety, and mag catch, plus a drop-in single-stage trigger and CMMG RipBrace. The 5/8x24 threaded muzzle accepts standard suppressors, and the package includes one 30-round Magpul PMAG. Total weight is 5.1 pounds with an overall length of 23.7 inches. Direct impingement operation and carbine buffer system ensure reliable function across ammunition types.
