Switching muzzle break = change POI?

[MilesDyson]

I'm changing muzzle breaks on a 556 11in anyone think I should have to rezreo?

You might. I had a 3MOA lateral shift going from a little bastard to a cherry bomb on a 6.5 grendel.

 

[MilesDyson]

Ok thanks. I'm surprised it's so much.

Your rifle may differ, but changing the weight that hangs off the end will most likely change barrel harmonics.

Changing to any type of unbroken muzzle should improve accuracy vs a broken muzzle. If you mean changing to a different muzzle BRAKE than you might see a little poi shift. Same thing when you are shooting with and without a suppressor.

I'm switching to a titanium from a steel. Same model.

Any reason not to at least check your zero?

I'm busy and mainly the range I normally go to is closed because CV. I will have to try somewhere new. But tanks for all the responses.

ive had a shift about 1mil when i went from a PVA jetblast to a 419 sidewinder.

You might get lucky, but I couldn’t get that lucky. A couple years ago, I took my brake off and cleaned the carbon out, and cleaned my muzzle. Took it to a PRS match that Sat, and couldn’t hit shit. MD let me re-zero during the lunch break. Shot much better in the afternoon. I was off about 10” at 400 yds. I didn’t change anything, just cleaned and replaced. I would’ve never guessed that it would have made that much difference.

Yeah, you'll have to re-zero

 

[GetReal]

I plan on re-zeroing when I change just about anything on the gun or load.

Yea I'm planning a day this week, I'll post an update

You might find these findings interesting , remember a great example of one guys barrel results.

It is definitively not out the realm of possibility. A solid zero check will make life good.

Changing muzzle device can/will change zero.
