A few questions on Muzzle Brakes

Hi Everyone,

Just got a new muzzle brake and fitted it to my rifle last night. Just had a few general questions about them.


1. How "level" do they need to be. I am confident i have it within 0.5% of a degree to the rifle. I would assume this is good enough? Every time i tried to get it perfect, I just ended up moving it when tightening.
2. Do you even need to remove it? IE cleaning the rifle? If not does it require any special attention when cleaning?
3. Once it is installed, is there anything i should do before shooting the first round though it make sure it is aligned with barrel properly and doesnt have any manufacturer defects? (I removed the bolt and looked down the bore and could not see any part of the brake. Put a rod down and seems fine, and also put a light in bore and the light appears to be an centered circle around the holes in the brake).

Thanks in advance
 
1. Whatever position best mitigates the recoil. You might find the gun likes to move in a certain direction, even with the brake installed. Orient the brake to counter that.
2. Not really. Might be a good idea to clean the brake every once in a while. But nothing special is needed.
3. Is your firearm/brake made by some crap manufacturer known to have terrible quality control? If not, then you'll be fine.
 
I like to pull my brakes every 200 or so shots. You'll find the carbon can be a real pain in the butt to get off the muzzle if you let it sit too long. And some brakes can cause a lot of build up!

If it is off of TDC by any amount the rifle will react not recoiling truly rearward, some lateral rotational movement will occur assuming it is not a radial ported brake.

A well engineered brake should never need to be removed as there will not be any sort of baffle or anything to collect carbon and copper fouling. IF you cannot see the muzzle, then you will need to remove it periodically for cleaning.

3. Once it is installed, is there anything i should do before shooting the first round though it make sure it is aligned with barrel properly and doesnt have any manufacturer defects?

A pin gage of the correct diameter will ensure you do not have a bullet contacting the brake.
 
Don't want to hijack this thread, but I have a brake question. pardon my ignorance, but is it ok to use a .30 cal brake on a 6.5mm barrel? I know the brake being slightly larger means that the bullet will not contact the brake but will having a larger brake affect the bullet trajectory at all?
 
The bullet will be fine. Significantly reduce the effectiveness of the brake though. Better off selling the 30cal and buying the right size.

Depends on the exit hole of the brake. Some manufacturers put overly large holes through the brake to ensure the bullet does not contact the brake. The better brakes have smaller tolerances between bullet and brake, in these the effectiveness is not tremendously effected.
In our brakes, using a 308 cal brake on a 6.5 will reduce the efficiency only by about 10%.
