Most Helpful Positive Review KVP Muzzle Brake
It works as it should. Tested out a suppressor with ASR mounting and it works just fine, granted it was a not a torture test as much as a fitment and function test. Also has a small hole located at the wrench flats which I believe could be used to pin and stake it to the barrel, so if if you had a 14.5 barrel you could permanently attach this muzzle device and have a 16 in barrel. Have fun!

Muzzle Brake

by Grimey556, Verified Owner from IN, United States Written on January 10, 2026
Phenomenal muzzle brake and works well with any silencer Co suppressor. If you are looking for an ASR style brake this one is half the price of silencerco and just as good. The taper is machined perfectly for a solid fit. Avoid Kaw Valley's other muzzle device which is the 3 prong flash hider at all cost! Makes an absolutely horrible noise when shooting and cycling the weapon from the tines not being offset. The loudest tuning fork you will ever hear.

Great product for a great price

by NEgunner, from NE, United States Written on January 7, 2026
Needed a larger bore muzzle break than what SiCo offers and this works flawlessly. Good look and great quality for my suppressors.

Smooth finish works as advertised

by RCH, Verified Owner from FL, United States Written on January 3, 2026
The KVP ASR mount muzzle device is an effective ASR mount. The mount is made well. Mounts smooth & the finish is a great look & is easy to keep clean after shooting suppressed.

Kaw Valley Precision ASR mount

by Lupe Ayala, Verified Owner from VA, United States Written on December 31, 2025
They really knocked out out the park with these !! All being .500 bore don’t have to worry about the caliber. Just the thread.

Better Than Original

by FourtyFive Snob, Verified Owner from TX, United States Written on November 26, 2025
I prefer Kaw Valley Precision ASR Muzzle Brakes to the “originals” because every one, regardless of internal threads, has a .50” bore. This makes them excellent for pistol caliber carbines where bore size and threads don’t always align with traditional caliber bore sizes and threads. Plus they cost less.

Better Than Original

by FourtyFive Snob, Verified Owner from TX, United States Written on November 12, 2025
I like Kaw Valley Precision ASR muzzle brakes better than the original manufacturer brakes because all of them have a .50” bore as opposed to a caliber specific bore based on internal threads. I’ve built quite a few pistol caliber carbines lately and the caliber/bore diameter doesn’t always match traditional muzzle threads/bore diameters. The .50” bore of the muzzle break, regardless of internal threads, takes this issue off the table. The price is also less than the original manufacturer’s and the function and quality are second to none.
