The Griffin Armament Taper Mount Minimalist Blast Shield (GAMMBS) was designed to offer significant concussion reduction for the end-user and other team members operating in the immediate vicinity. The Minimalist blast shield can also convert the Optimus silencer to a 7.9" 15.7-ounce mid-size taper mount configuration compatible with minimalist taper mount muzzle devices only. In the blast shield configuration, the minimalist brake shield is compatible with all taper mount muzzle devices.

Often team members in CQB environments experience a concussion from a muzzle blast that is not only deafeningly loud but also can cause prolonged headaches that can last for days afterward. Especially effective on short barrels, the Taper Mount Blast Shield directs concussive force forward. Ultra-strong 17-4PH stainless steel provides a robust material to withstand intense use and full auto fire without fear of failure. Flats on the rear of the device allow the use of a large adjustable wrench, strap wrench, or vise for removal if needed.

Melonite QPQ surface treatment provides an extremely hard, durable, and attractive finish.

Griffin Armament has continued to pursue product development that will enhance hearing safety in tactical and shooting sport situations. The Taper Mount Minimalist Blast Shield is a great product for those that would like to reduce the concussion of their muzzle devices.
