Griffin Armament Optimus 6 Dual-Lok | 6.68″ FDE

The Optimus’4 is a 6mm-bore additive-manufactured suppressor designed to reduce system backpressure through a high-flow baffle design while maintaining strong flash and sound reduction. A quad-tine flash-hider endcap is tuned with the baffle stack to deliver minimal visible flash. The Optimus’4 6 is offered in Dual-Lok taper-mount or Utility (HUB 1.375×24 TPI) configurations and is finished in high-temp FDE Cerakote. It is suited for precision shooting and range-based training.
