■The barrel is arguably the heart of any airsoft gun and determines various performance factors such as velocity (FPS), accuracy, and precision (consistency). Real steel guns have a single metal barrel while airsoft gun barrels come in two pieces, an inner and outer barrel. The outer barrel reproduces the appearance of a real steel barrel, while the inner barrel is the actual barrel which fires the BB. 

■The DELTA STRIKE Barrel Series is based off of the Tokyo Marui specification barrels. DELTA STRIKE fit a variety of guns and outer barrels, so you can choose from a wide selection of barrel lengths that best suits your own custom build!
