Timing for muzzle brake

[boyguan]

I got my 5r used and it has a threaded clamp on brake. I noticed that the recoil always pushes the rifle back to one side which makes it hard to stay on target.

Upon further investigation it seems that the brake ports is off about 5 degrees

Is it suppose to be exactly flat left and right?

I read online that the brake is sometimes off to compensate for bullet spin as well so it might be on purpose

If you're in so-cal, just take your rifle to Randall.

5 degrees loose or tight?
You could probably stone it for 5 degrees.
355 degrees, will need a machinist

You need to post a pic. It's a threaded clamp on?

Yes threaded clamp on. I can easily adjust it myself

[baih777]

You can play with the timing yourself.
Just wanna make sure it's not a eBay brake.

That's the principal behind the AK's slant break that is clocked.
I would try rotating it the opposite direction that it is now.

5 degrees misalignment of the brake is NOT going to cause a rifle to move to one side.
Your position behind the rifle is the problem.



When a rifle jumps to the left after the shot, your body is crooked to the left behind the rifle like the guy in the picture above.
When a rifle jumps to the right after the shot, your body is crooked to the right behind the rifle.

I’m from a rest but that does look like me. Do you have a photo of the correct way? I can’t imagine how it wouldn’t be a tad crooked

Is it only supposed to come back if I am aligned correctly

Are you shooting off of a bench with a front rest and rear bag or is this a bi-pod set-up?

Bipod and rear bag

I'll try a front bag next time and see if there is a difference

[Citadelgrad87]

I had Randall set me up behind my rifle. It's different than I was used to . Set up in line behind the rifle. A straight line.

I've found most benches don't allow you to get straight behind the gun like you should. The way benches are set up your shoulders almost always clocked to 10-4, when you really should be 9-3. You want your spine straight inline with the rifle.

A long but worthy read on the subject.

Great post, that's something I've honestly never even thought about, I'm going to try this next time I shoot!

I've often wondered why my AR-10 always seems to jump to one side or the other after each shot, even with the rifle configured to have very little recoil. I think this almost certainly explains it. I learned something new today
