Dead Air – Mojave 9 Fixed Barrel Spacer Stainless (PB139)

The Dead Air Mojave 9 Fixed Barrel Spacer (PB139) allows you to safely run your Mojave suppressor on fixed-barrel firearms by preventing booster damage and ensuring proper, reliable operation. Constructed from heat-treated 17-4 stainless steel with a durable copper-colored finish, this spacer delivers long-term strength and precision fitment.

Designed specifically for Mojave silencers equipped with the PB500 Booster Assembly, the fixed barrel spacer replaces the booster spring, mimicking direct-thread operation. This setup is ideal when running the Mojave on pistol-caliber carbines, subguns, or any platform without a tilting-barrel system.

Note: This spacer is not compatible with P-Series booster assemblies or pistons. It is only compatible with Dead Air Mojave pistons and the PB500 Booster Assembly.

Features:

• Protects booster assembly when using a Mojave on fixed-barrel firearms
• 17-4 stainless steel construction for strength and heat resistance
• Heat-treated stainless finish with copper coloration
• Simple, drop-in installation inside the Mojave PB500 Booster Assembly
• Offers an affordable method to adapt the Mojave for PCCs and subguns
