Crazy sound reduction by Angry pewman, October 10, 2022
I shoot 556 rounds indoor, which can become incredibly annoying. This md really does push all gas and sound forward and even at the indoor range it was much more pleasant to fire. FYI - THIS WILL WORK ON ANYTHING THAT USES A 1:2x28 thread pitch!!!!! ...

Guntec USA AR-15 Muzzle Comp by Boogie, Verified Owner, October 16, 2023
Pleasantly surprised with the quality. Would not call it a QD (Quick Disconnect) because it is treaded. Most QD's click on and click off. But the overall look and feel. Well worth it. The indoor range and gunsmith both loved the look and took picture...

Does what its supposed to do! by allcattle0hat, Verified Owner, August 17, 2021
I have this on a 7.5 AR pistol and I have a great time with it at an indoor range that I go to with no complaints or dirty looks. It pushes the concussive fireballs forward and away from you but it looks really cool! I dont think I would not use this...

Product Info for Guntec USA AR-15 Muzzle Comp w/QD Blast Shield

Guntec USAs new MRS AR15 muzzle comp is the end of the road for the average shooter. The MRS system utilizes a 2-port design minimizing muzzle rise. The MRS system employs a 1-port design effectively reducing muzzle climb and improving accuracy in rapid fire situations. The MRS AR15 muzzle comp also improves the recoil profile of the weapon, making faster target transitions. The MRS AR15 muzzle comp is aggressively braking muzzle climb to stabilize the rifle. Guntec USA muzzle comps also reduce muzzle rise, making them ideal for fast-paced, high-caliber shooting. Threaded with a 1/2x28 thread pitch, this muzzle device compensates for increased recoil over older models. An added benefit of the MRS Muzzle Comp is it also reduces muzzle climb, making faster target transitions. Threads into any of our threaded muzzle accessories such as our carbine length barrels. To install the MRS muzzle comp, simply turn the muzzle threads counter-clockwise until snug. Once tight, turn the bolt back towards the muzzle to ensure it doesn't come unthreaded.image
