The JK Armament 155 Hub Piston Mount is a direct-impingement conversion component designed for shooters running suppressed 9mm builds or upgrading their AR platforms with adjustable gas systems. This 1/2x28 threaded piston mount lets you swap between suppressed and unsuppressed configurations without swapping barrels, making it a smart choice for range shooters and hunters who want flexibility in a single rifle. Built from aluminum and stainless steel with a nitride black finish, it's engineered to handle the rigors of centerfire shooting while resisting corrosion and wear.
Piston-driven systems are popular among suppressors users because they help manage back-pressure and cycle consistency when running quiet. The 1/2x28 thread is the standard attachment point for most common suppressors and muzzle devices in the 9mm and rifle space, making this mount broadly compatible with popular cans and aftermarket components. The nitride finish gives it a durable, low-maintenance surface that stands up to both indoor and field use.
Whether you're building a dedicated suppressed 9mm upper, fine-tuning gas flow on an existing rifle, or simply want the option to run your suppressor with better reliability, this hub piston mount is a direct way to do it. It's the kind of component that serious shooters and gunsmiths reach for when they want proven, no-nonsense performance.

The 1/2x28 thread is the standard attachment point for the vast majority of 9mm suppressors and many rifle cans. Check your suppressor's thread specifications to confirm compatibility.
Yes—the hub piston mount is designed to allow you to switch between running suppressed and unsuppressed configurations on the same platform without changing barrels.
Piston systems like this one help manage back-pressure and gas flow when running a suppressor, which can improve cycling and reliability compared to direct-impingement systems that route all gas back into the bolt carrier group.
The nitride black finish is durable and corrosion-resistant, requiring only routine cleaning and light lubrication as part of normal firearm maintenance.
