One-Piece OTB Flash Hider for OPS/AE, 1/2×28

The One-Piece OTB Flash Hider for OPS/AE, 1/2×28 is a specialized, convenience-focused muzzle device. It integrates the flash hider and rear collar into a single piece so you can run AEM5/5K/5-30/5-30K and OCM5/6 suppressors without a separate muzzle device or custom collar work. It requires a barrel .750″ or smaller at the shoulder and at least 2.1″ of exposed barrel from the shoulder. If your barrel meets those specs, it is a clean, practical solution.

What It Does

A flash hider reduces the visible flash at the muzzle, which helps preserve your night vision and makes your position harder to spot in low light. On suppressor-ready designs it also serves as the mounting point for the suppressor, so it has to be precisely made and properly aligned with the bore.

Before You Order

Match the thread pitch to your barrel (1/2×28 is common on 5.56 and .22 rifles, 5/8×24 on .30 caliber rifles) and confirm the device is made for your suppressor’s mounting system. Muzzle devices should be installed, timed and secured exactly as the manufacturer specifies. If you’re not sure, have a gunsmith do it.
