Normally, I'll recommend a bull barrel when premium performance is desired, and there are solid reasons for this advice. There does also appear to be some evidence that muzzle brakes can improve accuracy, as well as making the shooting experience a little bit more comfortable, to say the least. Big boomers with low pressure like 45-70s and shot guns benefit the least.” [Editor’s Note: Roy is judging effectiveness by the percentage of recoil reduction rather than absolute levels of recoil. The latter benefit should have made a larger impact on me, and the fact I'm only now realizing how well braking helps accuracy is evidence of my slow-wittedness. var _gaq = _gaq || []; Rifle manufacturers are producing scoped rifles with built in muzzle brakes. However, it can change how the barrel whips during the barrel time. A brake reduces muzzle jump by using gas pressure to manhandle the barrel via directional ports, but how much pressure does a a .22lr have to offer? A muzzle brake, correctly installed, will have no direct effect on accuracy. This is a harmonic issue, and does NOT harm a rifles ability to shoot accurately. BSA1, Jan 28, 2018 #1. carbine85 Member. _gaq.push(['_setAccount', 'UA-6323545-2']); Will it make the rifle more accurate? So three very different purposes which leads me to ask what the purposes of the various flash hiders and muzzle brakes and how they affect accuracy. (Like the tank example), Incredible reduction of recoil. Sure does tame down a gun. I use it on a GAP10 G2 .308, a 5.56 Wilson Combat and even a AK47 SBR with NO muzzle rise and NO noticeable effect on accuracy. This is especially common for hunting rifles. What affect would having a muzzle brake installed have on accuracy of this load. The reason for decreased accuracy is that some hypersonic gases will precede the projectile as it exits the crown of muzzle. Muzzle brakes tend to effect a change in the accuracy of a rifle by affecting the harmonics of the barrel, moreso than by evenly distributing the gas cloud during the bullet's exit - that's pretty much what both the crown and compensators do. Its preferred ammo types printed in the .6- to .7-inch range. I have no idea what a comp will do on a longer barrel. The accuracy tuning function of the BOSS system is thereby retained. By cleaning the exit gasses off the bullet path, incipient yaw can be altered compared to a bare muzzle. In fact in some circles like NRA Service Rifle the competitors glue the brakes on the threads rather than tighten them down.

Depending on the accuracy capabilitys of the rifle you may not notice a difference. Bought this thing for one of my powderburners, but installed it on one of my PCP’s too. We took a brand new BRNO CZ550 rifle, installed a Nikon Monarch 6.5-20 scope on it. Muzzle brakes are controversial. As a hunting brake, this device directs the muzzle brake “blast” evenly and effectively, but it can kick up debris when used in … A well-controlled muzzle will yield very nice performance downrange. I like talking to this one guy a lot becuase of all his experience and knowledge with gunsmithing. I haven’t experience an increase in shot noise, just a redirection of it. The only way to get the base and threads perpendicular is to thread, not tap, them on a lathe.”, Share the post "TECH TIP: Optimizing Muzzle Brake Accuracy and Effectiveness", Tags: Gunsmithing, Harrells Precision, Muzzle Brake, Roy Bertalotto, Suppressor, Tuner Brake, I too have tested all sorts of muzzle brakes. _gaq.push(['_trackPageview']); Harrell’s Precision has made thousands of muzzle brakes, in many styles and port arrangements.
