Cleaning tuner - brake

[Link]

When you remove your tuner/brake does it change the point of impact when reinstalled?
How often do you remove it for cleaning?

Thanks Don

Every time I remove mine, it does move the POI but it is so slight makes no difference. Just my two cent Tommy Mc

I remove and clean mine every couple hundred rounds. I put witness marks on the top of the barrel and brake to get it installed as close as possible to the same place. If it changes the POI, it is less than the scope adjustments.

I have a machined in break on a 22LR and it will throw a shot after it gets fouled. I never thought about it when I ordered it.
More info . This is a screw on brake. - tuner.
I just don't want to have that happen with my 6bra.
I'm chasing a gremlin and thought this might be it. I will keep chasing.

As long as you reinstall it into the exact same position and setting, there should be no POI change. I have a Harrell's Tuner Break on my .308 and have not seen any detectable change in POI.

I remove my tuner break on every cleaning (typically at ~150 rounds fired) so that I can be clean the build up on the crown. . . and clean the tuner break as well.

I have a spongy, semi-rigid dowel of closed cell foam thats slightly smaller in diameter than the ID of my tuner (22 BR). It has a slit running down it that I push the ends of a 3" patch into, then wind it around. Note: Chem resistant foam. The resultant diameter of the dowel with the patch provide a slightly snug fit inside my tuner. I spray the patch area with brakekleen, run it down into the tuner while rotating it to keep the patch wound up, until it bottoms out against the muzzle. A couple of rotations and it usually comes out black, including where it contacted the muzzle. I then remove the patch and reverse it so that the black part is inside the winding and repeat. That usually comes out relatively clean and I'm done until the next match in two weeks. As sensitive as my tune is, I prefer not to remove the tuner to clean it or the muzzle. Admittedly, it does not include a brake, so i doubt my method would help clean the ports in a brake/tuner combo.
