What is the main function/purpose of a muzzlebreak on a AR-15 rifle ?
Does it aid in accuracy of the rifle by keeping down muzzle jump ? If I am wanting to buy an upper that I want mainly for accuracy, should I get a heavy barrel without a muzzlebreak or would I be better getting a medium contour barrel WITH a muzzlebreak ? Thanks. |

Muzzlebreak will have to be fixed, while a muzzle brake will slow down the recoiling rifle and help with muzzle rise.
The downside is increased blast that will damage your hearing with every shot, unless you run 30+dB hearing pro. For accuracy I'd get a heavy barrel with NO attachment on the muzzle. Anything on the muzzle can have some effect on accuracy. BS |

Muzzle BRAKE. There is no such thing as a muzzle "break" unless you broke your barrel.
A muzzle brake is for reducing recoil, a muzzle compensator is for reducing muzzle rise. You can have both in one device, for example a brake and a comp, you can also have a compensator in a flash hider, such as the M16A2 flash hider. The bottom of the A2 flash hider is closed, whereas the A1 was open and did not need to be timed. It also reduces dust signature when prone. You can't have a brake and an effective flash hider in the same device as muzzle brakes make tons of muzzle flash in low light. An example of a compensator by itself is the slant comp on an AKM. |

BRAKES are loud; unsuppressed is bad enough. I shoot a fair amount in reduced ambient light conditions, so flash suppression is more important to me.
That said, my most precision AR runs a brake.; I don't shoot that one at night or without serious hearing protection. |

For best accuracy you don't want anything on the barrel. Once upon a time Browning made a special compensator called BOSS. It could be tuned, to the specific load that was being used. I don't know what became of it, other than it never seemed to catch on with shooters. Posted Via AR15.Com Mobile |

My .308 A-Bolt with BOSS. The loudest thing I've ever heard, but it doesn't move when fired. |
