Made from 17-4 H900 Stainless Steel, this extension allows you to run longer muzzle devices with Bravo adapters that would not otherwise fit in some suppressors. It will give an extra 3/4″ of clearance for muzzle devices with any Bravo pattern adapter.
These adapters have a smooth exterior profile with 5 spanner wrench notches and are either Natural or finished in SOCOM Flat Black Moly Resin as a default.  Other color options are available to select from.  Please anticipate an additional 5-10 business days for color application.

These adapters install/remove with 1.5″ or adjustable spanner wrenches. We recommend the OTC 4791 adjustable spanner wrench, which will work with many mounts & adapters of varying diameters as well as some suppressor bodies.

    Bought this to help a suppressor I own clear a muzzle device. Excellent quality, fit my suppressor and my keymo device perfectly. Insanely quick shipping and even got the best gummy bears of all time. Have a about 600 rounds through the suppressor with the extension with zero issues. Has not loosened up on me at all. Great product.
