The Warface barrel extension tube is the perfect finishing touch for your airsoft rifle or pistol! Designed to match the barrel taper of the Steyr Scout and Scout Elite, the Warface B.E.T. is also at home on any barrel that is 14mm CCW threaded. The lightweight CNC-machined aluminum alloy construction adds minimal weight, so it will not interfere with the cycling of airsoft pistols or affect the balance of your airsoft gun.
