Dead Air PB446 Mojave Piston 45 Cal Fits M16x1 RH Black Nitride

The Dead Air PB446 Mojave Piston is a precision booster component engineered for .45 caliber suppressors on tilting-barrel handguns. This piston threads directly onto M16x1 right-hand barrels and integrates with Dead Air's PB500 Booster Assembly system to maintain reliable cycling and suppressor function across various host firearms. If you're running a Mojave 45 suppressor on a custom or European-threaded .45 build, the PB446 delivers the compatibility and performance you need without compromise.

Dead Air designed these pistons to work in conjunction with an internal booster spring, ensuring consistent operation even when barrel designs and spring rates vary. The black nitride finish resists corrosion and handles the heat cycling that comes with suppressed shooting. Whether you're setting up a precision .45 ACP handgun or troubleshooting cycling issues with your existing suppressor setup, having the correct piston thread pattern matters—mismatches lead to failed timing and reliability problems.

The PB446 is the right-hand M16x1 variant in Dead Air's piston lineup; if your barrel uses M16x1 left-hand threads or a different attachment standard, verify your barrel spec before ordering. This is a suppressor component, not a complete suppressor, and pairs with the Mojave 45 suppressor and compatible booster assembly hardware.

Specifications

Frequently Asked Questions

Is the PB446 compatible with my .45 suppressor setup?

The PB446 is designed for Dead Air Mojave 45 suppressors on tilting-barrel .45 handguns with M16x1 right-hand threaded barrels. Verify your barrel's thread pattern before ordering—using the wrong piston thread or chirality will prevent proper assembly and function. If your barrel uses M16x1 left-hand threads, you'll need the PB445 instead.

What's included with the PB446, and do I need other parts?

The PB446 is the piston component only. It is part of the PB500 Booster Assembly system and works with an internal booster spring; confirm you have all necessary booster assembly hardware and the compatible Mojave 45 suppressor before installation.

Can I use the PB446 on a non-tilting-barrel handgun?

No. Dead Air engineered this piston specifically for tilting-barrel .45 handguns. Using it on a different action type will not function reliably and is not recommended.

What does the black nitride finish do?

Black nitride provides corrosion resistance and durability to withstand the heat and wear from suppressed .45 shooting. It helps protect the piston during normal operation and storage.
