Features

The Griffin Armament PLAN-A Taper Mount Adapter allows suppressors with common HUB-style threads (such as 1.375×24 or 1.125×28, depending on the model) to interface with Griffin’s Taper Mount muzzle devices. Precision-machined from durable 17-4 stainless steel with a black nitride finish, it provides a secure, repeatable taper-lock connection for reliable suppressor alignment and minimal point-of-impact shift. Designed to expand suppressor compatibility, the adapter enables use with Griffin Taper Mount brakes, flash suppressors, and compensators while maintaining a lightweight and compact profile.
