This B.E.T. has a spring mounted inner-barrel, which actually extends the inner-barrel, resulting in increased muzzle velocity. This mock sound suppressor will make a gas powered Airgun shoot further and harder, while adding to its appearance.
This will fit a number of ASG pistols including the Duty 1, by removing the plastic thread protector on the end of the barrel. It doesn't come with a removal tool but a large allen wrench fits perfectly. This all metal extension is beautifully made and ads extra fps and coolness factor to your ASG pistol.
