How important is clocking the blackout

I mounted my blackout on my 300 blk ar barrel using shims, rock set and torque. But I could only achieve an 11:00 position with the top hole. Will this affect performance or accuracy?

Are you talking BLACKOUT Flash Hider, BLACKOUT Muzzle Brake, or BRAKEOUT?

In terms of the Muzzle Brake and BRAKEOUT, timing won't affect accuracy, but will/can affect recoil/muzzle rise direction.

If it were me, I would mess with shim combinations until I got it right.

The BLACKOUT Flash Hider doesn't need to be timed at all.

Shims + "top hole" to me says "breakout".

The hole in the top should be at the top. Remove the thinest shim and try again. Not all shims need to be used and they need to be used in the correct combination to time the brakeout and brake correctly.

If you have the Brake, then the holes should be on the sides (3 and 9 o'clock)

My bad it was the breakout. Since this will mostly be shot suppressed, no need to change it immediately, but if I was to do so, how would I get the mount off now that it's rocksett?

I have heard a bunch of people on here say that boiling water will break down the rockset. I'm just not sure how you would do it on a rifle barrel.

All you should need is an appropriately sized wrench.
Rocksett isn't all that strong (assuming you didn't paint it on). If you followed the instructions and just used a drop, it'll twist right off. If you used too much, you may need the water thing.
Just let it sit overnight in some water.
I've removed my flash hider and brakes many different times and never had an issue with just turning them off with a wrench.
Most times I don't even need to put the upper in a vise or anything.

What would the appropriately sized wrench be for a .30 caliber brakeout mount?

One that fits the flats around the wrench flats snuggly

I just use a big crescent wrench.

So sticking a screwdriver through the 3 and 9 o'clock ports and torquing it is a no no then.

Lol I'm sure AAC wouldn't mind the sale of a new brakeout

Torch it for a little bit. Makes it a bit easier to remove it after loctite/rockset

loctite, yes, rocksett not so much.

Rocksett is very heat resistant (up to 2015 degrees F)
It is water soluble and it's not insanely strong (unless you paint it on)
I have never needed to use heat (or even water) to remove anything that I have put on with Rocksett.
I have had to use heat and a cheater bar for red loctite though.

Good to know.
