The G&P WA M4A1 16 Inch Aluminum Outer Barrel is a replacement for the multi-piece barrel that comes standard on the Western Arms and G&P gas blowback M4 series airsoft guns. This one piece barrel is much more realistic, and being that it is constructed out of aluminum, it is incredibly sturdy while still surprisingly lightweight. If you want your G&P or WA M4 to live up to it's full potential, be sure to pick up the G&P WA M4A1 16 Inch Aluminum Outer Barrel.
