zero shift--muzzle devices

[DocRDS]

WHen you remove/clean your brake or muzzle device then replace how repeatable is your zero? My can was pretty repeatable, but that was a QD with a brake/FH attached.

Now I'm absolutly OCD so i'mprobably going to re-zero regardless

“was pretty repeatable, but that was a QD with a brake/FH attached”.

This sounds like you changed muzzle devices, as opposed to simply removing, cleaning, and re-attaching a muzzle device? Am I reading that wrong? If just removing, cleaning and re-attaching, id be shocked if there was any shift. Cleaning a heavily fouled can(heavier than clean) would cause a shift.

Rough weekend.

I meant removeing a muzzle device like a brake, cleaning, reattaching.

When I did my can, it was attached to the same muzzle device (QD FH/Brake), now I shooting brakes for competition and my 6mm need a lot more cleaning, so if i remove the Area 419 brake, clean it, re-attach, what kind of shift is expected.

My thought process is torque that bitch to the same value every time and you should see minimal if any zero shift. If you have enough carbon buildup to shift harmonics you have other issues.

Shouldn't see much at all unless you screw up clocking your ST brake. That doesn't guarantee you will see zero shift though.

A good rule of thumb for when you mess with *anything* is to shoot a round or two to verify zero. Otherwise you have a much higher probability of being able to share a 'one that got away' story... or becoming a member of the "add another tenth" club.

No doubt. I was trying to estimate if its something I can take care of at a zero board, or if I need a dedicated range session.

Area 419 uses a taper, as you know. Thats going to locate the brake perfectly, regardless of how much you tighten the knurled ring. Use your ocd to index it properly, and forget about it.

Handle it at the zero board. No separate range time needed.

 

[diggler1833]

Yes, a consistent and proven rifle setup shouldn't need more than a shot or two to verify that you have retained zero.

I’m mostly within a .1 or have the same zero when I take muzzle devices off for cleaning or travel and put them back on. I always check regardless of the history of consistency just out of caution, nothing more.

 

[TheJeanyus]

I have never noticed a shift when removing/reinstalled my Area419 brakes.

I don't like removing and replacing muzzle devices routinely, especially those with fine 28 or 32 thread pitches.
Subject to stretching enough that it'll fuck up the timing when torqued down.
I'll clean the carbon off the brake and crown with shop swabs, and if I run into hard to remove shit, I'll hang the rifle upside down with the muzzle in a small cup of solvent.

JMOYMMV.
