The B & T Non-RBS Sealed Endcap O44 / M20x1 Mainline Suppressor Hub is a precision-machined accessory designed to convert modular B & T suppressors from a flow-through configuration to a traditional sealed system for maximum sound attenuation. Featuring an M20x1 thread pitch and a 44mm outer diameter, this endcap eliminates the forward-venting gas ports of the Reduced Back Pressure (RBS) system, forcing all combustion gases through the internal baffle stack to achieve the lowest possible muzzle report. It is an ideal solution for shooters using bolt-action rifles or tuned semi-automatic platforms where maximum signature reduction is prioritized over gas blowback mitigation, providing a versatile performance upgrade within the B & T Mainline ecosystem.
