Different Point of Impact with Different Brakes

[TJNewton]

I've shot a couple thousand rounds through my VZ's with the slant brakes and they have been very accurate.  To minimize the cheek slap, I reindexed the slant brake to 12 o'clock and went shooting.  With bench rest, I found that at 50 yards the shots weren't even on paper.  Through trial-and-error I found that with the re-indexed brake, I was shooting about 12" high and 12" right.  I was finally able to zero it, but it took drifting the front sight over to the right as far as it would go.  Not a big deal, as it's zeroed, but after putting a couple of hundred rounds down range, I decided that the re-indexed slant brake did almost nothing for reducing cheek slap.  I don't like it.

I'm going to try perhaps the Slovak brake, and maybe either the PKM short, the A2, or the Phantom flash hiders.  Will the gun need to be re-zeroed for each brake or flash hider?  Is their a combo of a brake and a flash hider that won't affect the point of impact?  It would be nice to have something for day shooting and something for low-light shooting without having to re-zero with every switch.

My POI barely changed between the slant and Slovak

There will be slight differences is POI between brakes/muzzle devices.  Generally with flash hiders and muzzle devices with equivalent porting/exhaust venting all around (like Slovak Baffle), there is little to no change in POI.  Basically, if your muzzle device is porting exhaust gases in unequal directions, you'll see changes in POI when switching between.

However, the only true muzzle device that will not have any change in POI relative to raw barrel is the Czech thread protector...

That would explain why the slant brake has such radical differences in point of impact just by changing the angle.

Thanks for the info.

By the way, have you tried the Night Brake?  I've read opposing reviews -- some say that it hides flash well and others say it makes a fireball.  And then some say it makes a decent brake, and others that it does very little in that sense.

The supposed flash hider function of it is bs in my opinion.  I haven't tried it, but when your brake ports come before your flash hider, you're going to be blowing flames/flash to the sides....
