Honestly I have never done it before with a crush washer so it might work but it needs to go around nearly an entire 360 degrees....
Its sort of like a jerry miculek but with a crush washer and it doesn't have a space to put a wrench on it so I believe they use a metal punch running through the side openings to tighten the brake down on the washer. I would need to use a punch with a bar over the end to begin to crush the washer.... |

Crush washers are designed to let you go nearly 360 degrees around, if needed, so that part of it wouldn't be a problem at least.

I am just going to have to see the best way to leverage the rifle to torque the washer down....will report back later this week.
I am looking at an M4-72 severe duty compensator from Precision Arms if this doesn't work out....anyone have others they would recommend? I found a real miculek for $60 new. |

Ive never had one that didn't work with the right size washer...however that said

All you need can be found HERE.
FWIW, I put the Precision Armament M4-72 Severe Duty Compensator on my Aero Precision build, and it's a-w-e-s-o-m-e! |

Buy some shim kits.... I use them for all my muzzle devices... ( no suppressors ) MUCH easier to time a brake / flash suppressor.

Otherwise, what do you mean a "real" Miculek? The DPMS Miculek for $39 isn't real? It's a great value and effective, though not as effective as the M472. Though, if you have more money to blow, I'm also incredibly happy with my Area 419 Hellfire brake ETA: And yeah: Shim kits > crush washers |

Can't speak to the EFAB as I haven't tried it. I am going to try to get more info on the EFAB I saw it produced better results for recoil tests that the m4-72. |

If you don't have (or plan to get) the tools to properly time a muzzle device (you'll need a STRONG vice, barrel blocks, etc), then just get a slim jam nut (MUCH easier to install, as well as uninstall if think you may want to swap out later).
As for Muzzle devices themselves.. I don't have a ton of experience with variations, but can tell you I really like my Strike Industries King Comp and VG6 Gamma. |

All I can say is I hate Brakes. Fine for the shooter but hate the sound and the concussion if you are anywhere beside those things. These are gas operated guns and not like shooting .500 Nitro Express or anything. All my rifles use a standard birdcage flash supressor from .223 to .308. Just my preference of course.

VG6 Gamma 762.
PA M4-72 is my 1st choice. LANTAC Dragon 308/7.62 seems to go on sale frequently. |

I disagree, the most comprehensive test I've seen to date is from TFB, and here are the results. PA M4-72 performed the best. |

Take a look at the MBM tac-beast. $70 and runs with any of the big name brakes for reducing felt recoil. Down side (as with any of the effective brakes) is that it pounds anyone beside you...but its amazing.

a different set of tests
http://precisionrifleblog.com/2015/07/07/muzzle-brakes-recoil-results-for-6mm-6-5mm/ I realize it says for the 6 and 6.5, but some were just 308 brakes used. |

Well its that time when I am in the process of breaking down the upper to replace my gas block with my new SLR sentry 7 adjustable and I get to the part when I am about to remove the old block and suddenly it hits me....I have to remove the muzzle brake and I am without a replacement crush washer.
Since it was a PITA to get this one on I am now looking to simplify and replace the thing before I go any further. If I have to order a crush washer I might as well grab the new brake.... |

Well I bit the proverbial bullet and grabbed the Precision Armament .308 M4-72 and a necessary set of accuwashers from brownells. Crap forgot I should have grabbed my heavy buffer too, maybe its not to late to add it!!!!
I cannot wait to test this sucker out now! |

If you think your .308 is going to recoil like a 5.56 you are going to be sorely disappointed.
You should always buy shim kits for every caliber you shoot if you plan on adding muzzle devices to them. |

Ive already put several hundred rounds through it with basic muzzle brake on it so i bet it runs much less heavy with my new block, springco orange and heavy buffer than it did.
Good Luck to you too! |

PA M4-72 308 installed with PA accuwashers.

Now, $24 is expensive for “washers” but man those things are sick.
Much easier than a peel washer. |

The Accuwasher are nice but expensive. A crush washer is the easy and cheap way to time a muzzle device.

I love this PA M4-72 but man is it a flame thrower! My buddy was about 6 feet to my right and he about crapped his pants on my first shot! I moved 15 feet away to make sure he didnt get anymore of that. Be sure to stay clear of your fellow shooters on either side of you when using this sucker! The design aims the blow back towards you at a 45 degree angle so stay clear!
However, it reduces the felt recoil substantially compared to my cheap brake. |
