The JK Armament 155 Hub Piston Mount is a modular suppressor mounting solution engineered for 45 caliber and 10mm firearms. This piston mount system interfaces with .578"x28 threaded barrels, providing a direct-attach configuration that decouples the suppressor from the host firearm to reduce felt recoil and improve handling. Built from aluminum and stainless steel in raw finish, it's a robust choice for shooters running modern suppressor systems on pistol platforms.
Piston mounts work by allowing the suppressor to move slightly around the piston assembly as the projectile passes through, isolating the can from the gun's slide or action. This reduces the back-pressure transmitted to your firearm and can improve reliability, especially with pistols where cycling the slide matters for function. The .578"x28 taper mount is a common standard, making this a practical upgrade or replacement component if you're already running compatible barrels and suppressors.
The raw aluminum and stainless construction means you're getting a no-frills, durable mount without coating or finish—lightweight and corrosion-resistant where it counts. Whether you're building a dedicated 45 Auto or 10mm suppressor host, fitting a complementary barrel with the right thread pattern, or maintaining a precision setup, this hub piston mount is a direct mechanical solution that integrates your suppressor without proprietary conversion sleeves.
| Brand | JK Armament |
| Mount Type | Piston Mount (Hub) |
| Compatible Thread Pattern | .578"x28 |
| Calibers | 45 ACP, 10mm |
| Material | Aluminum and Stainless Steel |
| Finish | Raw |
This hub piston mount requires a suppressor and barrel with .578"x28 thread compatibility. If your suppressor and barrel both accept this taper mount standard, they will couple through this piston system. Verify your suppressor model and barrel thread spec before purchase.
This piston mount is designed for 45 ACP and 10mm firearms. Do not use outside the intended caliber range—use the correct suppressor rated for your caliber and this mount.
Piston mounts allow controlled movement between the suppressor and firearm, which can reduce recoil impulse and back-pressure. This is especially beneficial on semi-automatic pistols, where reduced pressure can improve reliability and handling.
This is the mount assembly only. You will need a compatible .578"x28 suppressor and a barrel with the same thread pitch. Check that both components are rated for this taper mount standard.
