| Looking around for a muzzle brake for my 7.62x39 ar pistol. Anyone have any links to a short one in 1/2-28 threads. I haven't had much luck. thanks |

Sorry, no links, and I'd be surprised that it has 1/2x28 threads. Every .30 barrel I've seen has 5/8x24 threads. There are short flash hiders that look just like the A2 style for the .223 –– I bought four by mistake. It has the same threads as my standard 5.56 ar. I put the A2 5.56 one on there to test it. I may be wrong on what thread that is however. |

just double checked, it has 1/2x28 muzzle thread

Gentry offers 7.62 brakes in 1/2-28. No personal experience with them, just ran across them once when researching something else. |

Conventional wisdom says you want the bore/opening of the muzzle device to be at least .030" over actual bullet diameter. .311" bullet + .030 = .341" You can use a 11/32 drill bit (.343") to check your clearance. If the bit will pass through the muzzle device, you're safe with a bullet. |
