Dead Air DA405 Ghost Piston Low Mass Piston .578x28 Nitrided

The Dead Air DA405 Ghost Low Mass Nitrided Piston .578x28 is a precision-machined piston assembly that unlocks the real modularity of Dead Air's Ghost-M suppressor platform. If you run multiple host firearms with different muzzle threading, this piston lets you configure your Ghost-M suppressor to work on .578x28 threaded barrels—no gunsmith trips, no new suppressors. Swap the piston, swap the host, keep the suppressor.

Dead Air engineered this piston with a low-mass design and nitrided finish, meaning it's built to handle the rigors of centerfire shooting while resisting corrosion and wear. Whether you're setting up a dedicated precision rifle or maintaining flexibility across a collection of hosts, having the right piston on hand lets you adapt your suppressor to your gun—not the other way around.

The matte finish blends into modern rifle aesthetics while the precision machining ensures a tight, consistent fit that supports the Ghost-M's reputation for effective, durable suppression. This is one of those accessories that pays for itself when you own multiple threaded rifles and want to consolidate your suppressor inventory down to a single, adaptable core.

Frequently Asked Questions

What suppressor does this piston fit?

The DA405 piston is designed for the Dead Air Ghost-M suppressor. It allows you to convert that suppressor to function on firearms with .578x28 threaded muzzles.

Can I use this piston on multiple rifles?

Yes. The piston itself stays in the suppressor; you attach the suppressor to different host firearms by threading the piston onto their muzzles. As long as your rifles have .578x28 threading, you can use this single piston and suppressor combination across them.

Why choose a low-mass piston?

Low-mass pistons reduce reciprocating weight in the suppressor, which can improve cycling reliability and reduce felt recoil impulse compared to heavier designs. Dead Air's nitrided finish adds durability and corrosion resistance.

What is the matte finish for?

The matte finish provides a professional, non-reflective appearance that blends with modern rifles and optics. It also offers some protection against minor corrosion compared to bare steel.
