The Otter Creek Labs OPS/AE Flash Hider is the muzzle device that an OPS/AE-pattern over-the-barrel suppressor mounts on. It is a highly effective flash hider that doubles as the suppressor mount. 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, Black Nitride 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.
