Over Barrel Shroud. Fits S&W threaded barrels and all other guns with a 1/2" 28 thread.
Quality made here in the USA of 6061 T6 aircraft aluminum. Item slips over the barrel giving it a very aggressive short barrel look and really sets off the look of the gun....very nice. This design also incorporates a muzzle brake front. Since this item is a muzzle brake it will extend your barrel 1.75" (Same distance as the standard bird cage brake)
Through Hole - 5/16" (for .223 and .22)
After running a few hundred rounds through this brake, I have to say I love the look, sound, feel and overall quality of this piece. I mounted it on my .223/556 patrol rifle and while the recoil difference is negligible (it's only a .223 after all) the sound is impressive. A much crisper and more pronounced boom than with my stock birdcage. Attached is a video of the shooting (no sound) but you can see that the gas is expelled forward and out evenly, keeping recoil manageable. Ill be buying another one soon. All in all a 5 star piece of equipment. https://youtu.be/1zk0gP8NzzI
