Otter Creek Arms Ocl-642 Ops Ae Flash Hider Raw Heat Treat 5/8X24

The Otter Creek Arms OCL-642 OPS AE flash hider is a precision-engineered muzzle device built for shooters running suppressor-ready setups on modern tactical rifles. This 5/8x24 flash hider pairs seamlessly with OPS Inc 12th Model AEM5 and OCM5 suppressors, making it an ideal choice for operators who want repeatable, reliable suppressor mounting without the guesswork. Built from H900 heat-treated 17-4 stainless steel and finished in black nitride, it's designed to handle the demands of frequent shooting and harsh field conditions.

The raw heat treat construction delivers durability where it counts—the material resists corrosion and thermal stress, critical when running a can regularly or shooting extended strings. Wrench flats mean you can install and service it without specialty tools, and the pre-drilled hole accommodates pin-and-weld mounting for jurisdictions or preferences requiring a permanent setup. Whether you're building a dedicated suppressed rifle or switching between hosts, this is a straightforward, combat-proven solution from a maker known for precision manufacturing.

This is purpose-built hardware for the shooter who already runs a quality suppressor and wants a flash hider that simply works. No marketing flourish, no surprises—just a solid piece of steel that does the job and lasts.

The OCL-642 is machined from 17-4 stainless steel in the H900 heat-treated condition, finished in black nitride. This combination provides strength, corrosion resistance, and durability under thermal and mechanical stress.
