Muzzle Brake

[skyungjae]

How did this happen? That looks almost like an XM177E2 style flash suppressor. Not part of the barrel, so how did the end blow up?

It probably happened when the user improperly installed that magpul furniture. Magpul stuff tends to cause stuff to go boom.

Some sort of blockage.

That muzzle brake issue is baffling. See what I did there?

Some sort of blockage.

That's a given. But what kind of blockage in a flash suppressor like that? Mud would just blast out on the first shot. And the rifle looks clean, so not that.

I don't understand how that one even happened. The dude had a rock jammed in his flash suppressor or something?

My guess is someone thought it would be funny to put the muzzle under water.

Maybe it says what happened here:

I'm answering my own questions, given lack of guidance.

Anyways, here's two more questions for you guys (Randall).

#1 what is the consequence of an oversized hole in the brake? as in, 338 size hole and using it on a 6.5 (just an example)

#2 if I can buy a brake (that I otherwise like) that is a 1" tube for a gun with a .75" barrel, nothing is stopping me from putting a 1/8" chamfer on the brake to mate up to the barrel, yes? given that, for aesthetic purposes, what angle do you recommend I set the compound to? I assume 45 degrees will NOT look attractive. or will it? what's a common angle to put on a brake body?

Edit: actually three questions. If I time the brake myself, what do you suggest I time to? 10 degrees off TDC when screwed in by hand? Like a revolver barrel?

Thanks for the input on the 3 port Ross Schuler brake!

On your earlier question YES the forward facing holes are for noise reduction.
On the larger diameter hole you lose some efficiency but not that much. The larger diameter acts like an expansion chamber and usually the rear most ports do all the work.
And the larger diameter of the brake itself is a plus because it gives the escaping gasses a larger place to impinge upon.
On the timing issue if you go to far you can always back off the brake and peen the shoulder on the barrel.
It works the same way as tightening up the main caps on an engine.

Cool. That just leaves one question. What angle do you suggest i set the compound to to transition the larger diameter brake to barrel diameter? Looks like maybe 30 degrees in your pic?

Try more like 10-15 degrees.

I think you missed on the picture. We are interested in what is left 1 foot.

Thank you sir.

Standish, I'll bet that Playmate is from the Bush Days....and I'm not talking presidents.

Now I am looking at a brake that has a 1-14" thread at the base. The idea is you can shroud the brake to direct blast forward, away from the shooter. Like combining a brake AND a linear compensator.

Not very attractive, but it looks like it would be quite effective.

Would it reduce the effectiveness of the brake at all?

[Whiterabbit]

Also, they make a mini "Ross Schuler" brake like that, or a "weatherby accubrake" style brake. Any comment on which of those two styles is more effective?

Assuming dust kick-up was not an issue.
