ZEV Technologies 5.56 NATO Muzzle Device - Black 1/2x28 Thread
- Caliber-Gauge:
- 223 Remington / 5.56 NATO
The ZEV Technologies 5.56 NATO muzzle device in black with 1/2x28 threading is built to handle two jobs at once: taming muzzle flash and controlling upward recoil. If you're running a modern AR-platform rifle and want to keep your sight picture steady and your muzzle signature reduced downrange, this is the kind of purpose-built hardware that makes a real difference. The design extends over the barrel shoulder to hide the crush washer and create a clean, finished look—no janky hardware showing.
Installation is straightforward: wrench flats are machined into the body for a secure grip during mounting, so you can get it on square and tight without fumbling around. Just keep in mind that this device needs room to sit on your barrel. It's only compatible with barrels featuring a .750-inch or smaller gas block journal; if your barrel has a larger journal, the muzzle device body will interfere with the shoulder. Before ordering, verify your barrel specs to make sure you're in the clear.
ZEV Technologies built this muzzle device for shooters who take their rifle setup seriously—whether you're zeroing at the range, hunting, or running drills. The flash-reducing properties and recoil management combine to help you stay on target, shot after shot.

Frequently Asked Questions
Will this muzzle device fit my AR-15 barrel?
This ZEV muzzle device is compatible with 5.56 NATO barrels that have a 1/2x28 thread and feature a gas block journal of .750 inches or smaller. If your barrel has a larger gas block journal, the body of the muzzle device will contact the barrel shoulder and won't fit properly. Check your barrel specs before purchase.
Do I need to buy a crush washer separately?
No. The crush washer is included with the muzzle device, so you have everything needed for installation right out of the box.
What's the benefit of flash suppression on a muzzle device?
Flash suppression reduces the visible muzzle flash signature, which is especially useful if you're shooting in low light or in environments where muzzle flash can degrade your vision or give away your position. Combined with the muzzle rise reduction this device provides, you get better control and faster follow-up shots.
Do I need special tools to install this muzzle device?
The integrated wrench flats allow you to install and tighten the device with a wrench, making the process straightforward and ensuring a secure fit. An armorer's wrench or adjustable wrench will work for installation.
