Questions & Answers
I have an AR chambered in 7.62x39 but the barrel threads is 5/8x24. And it says that the .308 caliber thread is the 5/8x24. Can I use the .308 instead Expert Answer

No, because 7.62x39mm bullets are commonly up to .311 inches in diameter.

I bought the 556 hex brake for my daniel defense ddm4v7 and it's 1/2 28 tpi.Thats also what the muzzle brake says. Some reason it doesn't fit. Help me Manufacturer Answer

Please contact the Phase 5 customer service department regarding your specific issue. The thread pitch for the FATman Hex Brake is 1/2x28TPI, so it should work with that barrel.

Helpful Positive Review Absolutely love it! by JC, Verified Owner, December 6, 2023
My favorite brake to date. As soon as I start shooting the heads start turning and people are coming over to see what in the world I am shooting lol. If you like attention while youre shooting then you'll love this thing. Very fun to shoot with.

Helpful Positive Review Works awesome by Maximiliano Garcia, Verified Owner, April 7, 2018
This brake is on the pricy side but it works excellent. It slips over the barrel about an inch and is pretty aggressive looking. It does come with a crush washer and pretty easy to get the timing done.

Helpful Positive Review Can't go wrong with a fatman by Dominik, February 18, 2019
Brutal , great looking muzzle brake, will hide nicely under free float handguard. People shooting next to you will hate you because blast will go right into their faces. Anyway it looks bada## , finish could be a little better but let's not be picky,...
