Our muzzle brakes are made of the finest materials - 41L40 steel and 416 stainless, and single point tool threaded on a CNC lathe to insure the threads are square with the end and bore. They are never tapped. We have a brake to fit any barrel from .550 with 7/16 threads to 1.5 inch with 1-inch threads. They come in both - Tactical and Spiral Port. Stand and Threads are 32 TPI. We also have 24 TPI x 5/8 for your factory threaded barrels and 28 x 1/2 for the AR's.
Let's be frank. After having made tens of thousands of muzzle brakes in dozens of styles over the last 25 years, we know what works best. If there were a better brake, we would be making it. No muzzle brake made today, at any price, will reduce recoil any better than ours. Independent tests have shown that muzzle brakes with price tags up to 3 times that of ours, and advertised as being much quieter, are in fact only 4-to-6 percent quieter than ours. They also aren't as effective in reducing recoil. That's the trade-off - if they are effective, they are noisy. Don't be duped into buying a "quieter" brake for 3 times the price!
Call us for the right brake.
