Muzzel Brake

I have the Dlask arms A6 and it is considerably better then the stock brake. There is noticeably less recoil and second shots are very quick as there is just about no muzzle jump.

Thanks CZ, does it require any tuning for ex: 1:00 postiton for right handed shooting or 11:00 for left handed?

I seen the close up pic and there is an arrow pointing upwards and is there shimms included?
 
They include a crush washer but no shims and I just cranked it down until the the washer and brake where touching then tightened until it was level. I haven't noticed any side to side movement so I put the top at 12. My brake didn't have the arrow pointing up on it but its very obvious which side is up.

I also got the AR stock adapter and sling attachment plate from Dlask when I ordered the brake and if your thinking about it all i can say is wow they spent a lot of time getting the right profile and did an awesome job machining it.
 
I have the Dlask, it does a great job on muzzle rise and recoil, but the blast and increase in noise is a real consideration. I have to double up on the hearing protection.
 
^^That's not a brake.

I've tried the Dlask A6 on both the VZ 58 and the AR. It does an incredibly good job at mitigating recoil and muzzle rise, and is very expertly designed.
 
It does work very well, but it isn't perfect. I had one on my m14 and noticed pitting on walls of the brake after firing only 250 non-corrosive rounds. Perhaps the soft metal won't be affected by .223 rounds. As well, the flats for the wrench are just off center, so the brake always looked out of index.
 
The pitting likely isn't caused by corrosion. It's caused by erosion, and it's normal. When you shoot a rifle you have super heated gasses and unburnt powder particulate flowing out of the muzzle. A muzzle brake deflects these gases and particulate based on the design of the device. This effluent is traveling at speeds faster than the projectile and will cause erosion of any muzzle device. It's akin to sand blasting and will happen to any muzzle device over time including brakes, comps, suppressors and even flash hiders. SBR's are notoriously hard on muzzle brakes, is your M14 barrel a shortened one?

Below is a pic of erosion of an M14 flash hider taken from an M14 forum. Given enough rounds it would erode right through the leading edge of the device....

My m14 is a shorty and I understand the process, but I wasn't expecting to see damage so fast. Perhaps I'm just annoyed because Dlask did a piss poor job of threading the barrel and crudely reaming out the brake to accommodate .30 cal.
