The B & T VERS36 Modular Endcap M33x1 Cal. 7.62mm Mainline Suppressor Hub is a precision-engineered accessory designed to optimize the performance and versatility of the modular VERS36 suppressor series. This endcap features an M33x1 thread pitch for secure attachment to the suppressor body and is specifically bored for 7.62mm/.308 caliber projectiles to provide maximum sound reduction and flash signature management when using .30 caliber platforms. As part of the B & T Mainline accessory ecosystem, it allows shooters to tailor their suppressor's exit aperture to their specific host firearm, ensuring that the Reduced Back Pressure (RBS) system and internal star baffle architecture operate at peak efficiency without the excessive clearance of larger-bore endcaps.
