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!

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.

Great design

by GB, Verified Owner from TX, United States Written on September 12, 2025
I believe this is the superior design for an ASR muzzle device, simply because it does not have to be timed. Most of us are using this as an attachment point, and as such, it's much more efficient.
