![]() ![]() Vented upward, it will result in downward force on the barrel, and essentially I recorded this with a high-speed camera and then plotted how a laser Moved to under recoil relative to the point of aim, indicated by the redĬircle. The graphic below shows a glimpse of the resultsįor my staying on target test. Much gas upward, causing the barrel to be forced downward, which can hurt more A couple of the muzzle designs redirected too But, as I learned through my testing, youĬan certainly overdo top ports. Local machine shop to have a couple top ports drilled into them. In fact, I considered taking the APA brakes I owned into a Owner of American Precision Arms, and I started hounding him to start offering top Through my research project, I got to know Jered Joplin, the But, if you can stay on target and spot your own impact, you’d be able to see if you are slightly off the center of the target in one direction or another, and then apply a correction to center your next shot. If you aren’t able to see your bullet splash you’re missing the most critical data you can have, and you’ll basically be sending the next shot blind and just hoping it connects. Staying on target allows you to spot your own impact, which is the most important feedback you can have as a shooter. Many veteran shooters see staying on target as the most important features when it comes to a muzzle brake, even more than recoil reduction. The data showed that in that aspect they were good but not great. The only area where I saw room for improvement in APA’s design was when it came to helping you stay on target. I still have all of the muzzle brakes I used in that test, so IĬould obviously choose to run any of them on my rifles – but after analyzingĪll the data and getting hands-on experience with all the designs, I chose toįat B* Gen II muzzle brakes on my magnum rifles, like myģ00 Norma ELR match rifle. That the muzzle brakes from American Precision Arms were top performers across The full results of that muzzle brake field test here, but the data from those tests clearly showed Ground signature & muzzle blast using a veryĬreative way to visualize how gas was directed.Professional precision sound level meter that cost several thousand dollars Noise level at the shooter’s position using a.Ability to stay on target using lasers and.Recoil reduction using a very high-speed.Most important to precision rifle shooters: ![]() The muzzle brake field test focused on quantifying theĭifferences of the muzzle brakes in terms of performance in the areas that were But, I was also trying to help manufacturers understand the importance of testing their designs and give them some insight into which features seemed to produce the best results. My goal was to equip fellow long-range shooters with as much hard data as I could reasonably gather to help them make an informed buying decision for their application. Very little objective research with controlled and repeatable experiments had been done on muzzle brakes up to that point. I conducted several objective tests over a few months to quantify the performance of 20+ muzzle brakes designed for precision rifles in 6mm through 30 caliber. A few years ago, I conducted a massive amount of primary research related to muzzle brakes ( view results). ![]()
