Griffin GAOP6UMFDE-W Optimus 6 | 6mm HUB | 6.02″ FDE

The Optimus 6 is a 6mm bore additive-manufactured suppressor engineered to reduce system backpressure through a high-flow baffle design while providing measurable sound and flash reduction. The suppressor uses a tuned quad-tine end cap together with a low-backpressure baffle stack to minimize visible muzzle flash. This listing is for the Utility Mount (HUB) variant finished in Flat Dark Earth Cerakote and built from 17-4 stainless steel.

Applications for this product include precision/competition shooting with 6mm projectiles and use on 5.56mm platforms where reduced backpressure and low flash are desired. The Utility (HUB) mount configuration is intended for users who will supply a compatible muzzle device or hub insert separately.
