I am trying to find a muzzle brake for my 6.5 Grendel with no luck. The threads are hard to match. The barrel is threaded 9/16"-24. Any ideas? Sabre Defence - scroll down...it's the Tactical Gill-Brake (3rd item from the top). Cheers, Sakic #19

Gill Brake PWS AAC Vltor A-2 Gemtech Yep, all of those offer some with the 9/16"x24 thread. Here's a Smith Vortex with those thread count Smith Vortex 9/16"x24 tpi |

Thanks everyone. My buddy found a guy that can "open" up a standard flash hider to the new diameter and changed the threads. Its more economical this way.

This is actually one of the reasons the 9/16s size was chosen.

It seem really dumb that AA would choose 9/16x24 for their thread pitch when nearly every .308 and 6.8 muzzle device is already threaded 5/8x24.
 I'm actually strongly considering cutting and rethreading my AA barrel to rectify this tardery.

It allows you to use standard-sized 5.56 devices, which are less "clunky" than using .308 devices. Sure, that's purely aesthetic, but there it is. Of more importance, is that using 5.56-sized devices allows COTS applications with blank-firing adaptors, etc.
All things considered, 9/16-24 was the wisest choice. John | 6.5 Grendel: The Tier One AR Cartridge. | www.65grendel.com |

All the brakes made in that factory thread are around $90 or more. I wanted to use a highly regarded $30 brake. All in all the brake will cost me $40+ ship both ways. |

Regardless, both are common to get. |

Except that all my FAL's are LH threads.
I really wanted a PWS FSC30, but just ordered a Vortex from Brownells instead. So, thoughts of chopping the barrel are currently on hold. |

This really annoys me about the grendel. If I want to put a supressor on it I have to cut the barrel and have it rethreaded.

I just cut mine down for new threads. I was easier to fine used muzzle devices on the EE with that thread pitch.t |
