Gemtech 5.56 ETM Flash Hider, 1/2-28

This Gemtech flash hider (brand part no. 13815) is built for reliable alignment with Gemtech’s ETM-equipped suppressors, measuring 2.375 inches and pre-dimpled for a gunsmith to pin and weld it to a 14.5-inch barrel, bringing the total length up to the legal 16-inch rifle minimum. Gemtech designs the ETM interface to virtually eliminate the carbon lock-up that can occur between a flash hider and suppressor after sustained firing. This AR muzzle device is an ordinary Title I muzzle device, not a suppressor itself.

Frequently Asked Questions

Why is this pre-dimpled? The dimples give a gunsmith an exact reference point to pin and weld the device to a 14.5-inch barrel, bringing total barrel length up to the legal 16-inch rifle minimum.

Is this flash hider itself an NFA item? No. It’s an ordinary Title I muzzle device; only a suppressor mounted to it would be the NFA-regulated item.
