This Aluminium constructed outer barrel is designed for the M4/M15/M16 family of Airsoft Electric Guns, and comes included with a short extension piece to convert your outer barrel from a CQB length (10.5") to Carbine length (14.5"). Both barrel pieces feature a 14mm CCW thread at the end so that you can still install your favourite muzzle devices such as suppressors and tracer units, regardless of which length of barrel you currently run. The outer barrel also features grooves at the front for the installation of an A-Frame front sight.
