The Optima family is our top-shelf silencers which are in a modular design making it possible to change the two front modules to suit another calibre within the .224 - .375 range, or simply remove one to make it shorter. Extremely durable due to the hybrid design: A hardened aluminium alloy designed to handle high temperatures, and a hardened heat treated stainless steel core that will secure the silencer’s lifespan to meet most shooters’ needs.
