Dead Air Mojave Fixed Barrel Spacer PB139

Using this fixed barrel spacer in a Mojave silencer protects the booster assembly from potential damage
due to the reciprocation of a spring-loaded booster on a fixed barrel. While we’d first recommend using a P-series fixed mount, Keymicro, or Xeno mount on your Pistol caliber carbines, The Mojave Fixed Barrel Spacer provides an easy and inexpensive method
of converting a Mojave silencer equipped with a booster assembly for use on a fixed-barrel firearm. 

The Mojave Fixed Barrel Spacer is used to mimic the operation of a direct thread mount.
It is conveniently installed around a Mojave piston in place of where the booster spring sits, inside of your Mojave Booster Assembly (PB500) for use on guns with fixed barrels, rather than with tilting-barrel hand guns.
