The Otter Creek Labs OPS/AE Muzzle Brake is the muzzle device that an OPS/AE-pattern over-the-barrel suppressor mounts on. It keeps the iconic OPS Inc brake profile with a few small tweaks and better material and finish. Machined from H900 heat-treated 17-4 stainless with wrench flats and a pre-drilled hole for pin and weld. This is the 5/8x24, Raw heat treat version.
With a muzzle device mount the suppressor is located by a collar further back on the barrel, so you also need the M4 Collar or SPR Collar that matches your barrel profile. If your barrel has at least 2.05 inches exposed from the shoulder and is .75 inch or less in diameter, the one-piece OTB Flash Hider or OTB Muzzle Brake does the same job with no collar.
