Product Overview
The Dead Air Ghost/Pyro Pistol Piston 1/2×28 is a suppressor-support component intended for a specific mounting, attachment, alignment, service, or configuration role. Suppressor accessories are highly system-specific, so the suppressor model, host firearm, barrel thread pattern, mounting standard, caliber, and manufacturer part number should all be confirmed before purchase.
Key Features and Specifications
- Product Type: Suppressor Piston
- Thread Pattern: 1/2×28
Why These Features Matter
Product Type: Suppressor Piston
Correct identification matters because pistons, boosters, fixed mounts, front caps, muzzle devices, spacers, and adapters perform different jobs.
Thread Pattern: 1/2×28
Thread pitch and direction must match exactly. An incorrect pattern can damage the barrel, mount, or suppressor and can create an alignment hazard.
Choosing Pistol Pistons, Boosters, and Fixed-Barrel Components
A tilting-barrel semiautomatic pistol commonly requires a compatible piston and booster assembly so the firearm can cycle with the suppressor attached.
Fixed-barrel hosts do not use the booster in the same way. Depending on the suppressor system, a fixed mount or fixed-barrel spacer may be required instead.
Match the piston thread pattern to the host barrel and verify that the piston, booster housing, spring, and suppressor model are approved to work together.
Do not substitute a fixed-barrel spacer for a piston or use a booster configuration on an unsupported host. Follow the suppressor manufacturer chart.
Installation, Alignment, and Maintenance
Unload the firearm completely before installation or inspection. Follow both the firearm and suppressor manufacturer instructions.
Clean the barrel threads and mating surfaces, then install the component using the specified torque, shims, timing method, and thread treatment. Do not improvise with crush washers unless the manufacturer expressly permits them.
Verify suppressor alignment with the correct equipment before firing, especially after changing mounts, muzzle devices, adapters, front caps, or host firearms.
Inspect threads, tapers, locking surfaces, pistons, springs, caps, mounts, and fasteners for carbon buildup, wear, deformation, looseness, or damage. Replace any component that no longer locks or aligns correctly.
Best For
- Owners matching an accessory to the exact suppressor and host-firearm system
- Direct-thread, QD, HUB, piston, booster, 3-lug, or muzzle-device configurations identified by the manufacturer
- Users who will verify thread pitch, caliber, alignment, torque, and installation requirements
TRA Take
For pistol suppressor setups, the operating system matters as much as thread pitch. A correct piston with the wrong booster or host type is still the wrong configuration.
Frequently Asked Questions
What type of suppressor accessory is this?
This product is classified as a suppressor piston based on the catalog information.
What thread pattern does it use?
The listed thread pattern is 1/2×28. Confirm thread diameter, pitch, direction, and barrel shoulder requirements.
Is this accessory an NFA-regulated suppressor?
No. This listing is for an accessory or mounting component, not a serialized suppressor. Standard non-serialized accessories generally ship directly where legal.
Is professional installation recommended?
Professional installation or inspection is recommended whenever the part affects muzzle-device timing, suppressor alignment, mounting security, barrel threads, or safe projectile clearance.
How should alignment be checked?
Follow the suppressor manufacturer procedure and use appropriate alignment equipment before firing, especially after changing mounts, adapters, muzzle devices, caps, or host firearms.
Can similar-looking mounts be substituted?
No. Similar appearance does not confirm compatible dimensions, thread pitch, locking geometry, or caliber clearance. Use only manufacturer-approved combinations.
What is the manufacturer part number?
The manufacturer part number is DA401.
Shipping and Installation Information
This listing is for a non-serialized suppressor accessory and generally ships directly where legal. It is not a suppressor and does not itself require an NFA transfer. Some muzzle devices, adapters, tools, or components may be restricted by destination or intended configuration. Confirm lawful use and follow all manufacturer installation, torque, timing, alignment, cleaning, and inspection instructions.
