The PTS Mega Arms MKM CQB GBBR replicates the unique design of the Mega Arms MKM AR-15 platform. The Mega Arms MKM platform mates the rail with the billet receiver in a proprietary manner that makes it as rigid and sturdy as a monolithic (1 piece) upper yet remains extremely lightweight. This design combined with PTS’s precision engineering and faithfulness to realism makes this a very high quality and durable airsoft replica. This CQB model with its ultra-lightweight 9 inch Keymod compatible rail and 10.5 inch barrel is the perfect airsoft gun for handling in any confined space and close proximity combat environments. The PTS Mega Arms MKM CQB standard equipment also includes our proprietary design PTS Enhanced Polymer Grip, Enhanced Polymer Magazine, and Enhanced Polymer Stock. Features: EP Grip (EPG) – ergonomically designed for excellent comfort and a firm angled grip for maximum recoil control. EP Stock (EPS) – a simple yet highly functional collapsible polymer stock.
