The PLENUM is a precision-machined suppressor mounting adapter designed around the HUB Taper interface, providing a more secure and repeatable lockup than traditional straight-thread HUB mounts. By combining a 1x16L ACME thread with a true taper engagement, the PLENUM promotes consistent axial alignment, reduces tolerance stack-up, prevents carbon locking, and resists loosening during use. Clean geometry and tight tolerances ensure predictable installation and removal, making it a reliable foundation for HUB Taper compatible suppressor systems.
