The B & T VERS36 Modular Endcap M33x1 Cal. 5.56mm Mainline Suppressor Hub is a specialized modular component designed to enhance the sound suppression and flash reduction of the VERS36 series when used with 5.56mm/.223 caliber firearms. By reducing the exit aperture to match the smaller projectile diameter, this endcap minimizes the escape of expanding gases, effectively lowering the muzzle signature compared to larger-bore standard configurations. It features a robust M33x1 thread pattern for a secure, repeatable interface with the suppressor body and integrates seamlessly into the B & T Mainline ecosystem, offering shooters a simple way to optimize their modular suppressor for dedicated small-caliber use without sacrificing the durability or gas-management benefits of the Reduced Back Pressure (RBS) system.
