Hey, Alex. I am not knowledgeable on this subject, but i have some doubts about ground signature. I couldn’t get other sizes for these tests. Most of the brakes in this test don’t have significant ground signature, but at least one of them does … which is apparent in the high-speed photos. You may also be interested in the AR-15 Drop-In Trigger Roundup here. I also talked him into bringing down his really expensive sound meter setup with him, and that is how I was able to measure the noise level on all these muzzle brakes. GO TO PRB Muzzle Brake Test SUMMARY » Recoil Reduction Cal created a system to directly measure the entire recoil force signature of each muzzle brake using high-speed sensors. But it’s an interesting idea! Well, Heath, I couldn't disagree more. Thanks for sharing, Greg. They may be great, I just don’t have any experience with them. It included several objective tests to quantify the performance of 20+ muzzle brakes designed for precision rifles in 6mm through 30 caliber.

This is one method of quantifying rearwards recoil energy. . Is there any evidence that the improved harmonics of the rifle by adding a muzzle break have a positive impact on precision if you take the shooter out of the equation? I’m glad you like my style. Thanks, Adith. I committed to creating a system using high-resolution sensors capable of recording hundreds of data points in a single shot … and I pulled it off. The function of the muzzle brake is to redirect the propellant gases released when the bullet is fired. That’s a great idea. The moving parts might affect how reliable or durable the brake is, because there can be significant carbon build-up on a muzzle device. I can understand the confusion on the pricing chart.
