1.375-24 Bravo (HUB, “ASR”) 3/4″ Extension

$68.00

Description

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.

*Stacking extensions is not recommended, and if done for the purpose of increasing blast chamber volume could be considered the making of a new silencer by ATF.  If you choose to do so, it is at your own risk.

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.
