Description
**Turn a non-threaded Remington 597 barrel into a 1/2x28 host. Precision slip-on fit clamps with six set screws for a secure, concentric mount for brakes, comps, and suppressors where legal.**
The Gen 2 Slip-On 1/2x28 Adapter lets your non-threaded Remington 597 run modern muzzle devices—no machining required. It is precision-fit to the factory 597 barrel profile for a secure, concentric install. Slide it on and lock it down with six set screws to add industry-standard 1/2x28 threads out front. Use it with your favorite muzzle brake, compensator, flash device, or suppressor (where legal and properly registered).
This Gen 2 model is a major upgrade over our original: precision-machined from 17-4 H1150 stainless and finished in black nitride for exceptional hardness, wear resistance, and corrosion protection. The result is a tough, repeatable mount that installs easily and holds true.
