POI shifted after muzzle brake removal

[Cheeseburger1976]

just bought a new NOMAD suppressor direct thread, had to remove my dead air KeyMo from the old Sandman L it was obviously on their tight. I Put the brake in a bench vice, twisted the rifle while the brake was being held, took some force, but I got it off. Took the rifle out to shoot today with the new dead air nomad direct thread. Point of impact is now 6 inches high, I’m fully bottomed out on my zero stop Nightforce, which I think I can adjust but just curious if I could’ve damaged something.

I would expect a poi change by hanging the extra weight on the end of the barrel but damage I have no idea.

My previous suppressor was on there. It was a Sandman L, twice the weight of the new can. That’s definitely not the issue.

You don't want your scope bottomed out. How steep is your rail?

This rifle was an absolute Lazer before I removed the muzzle break and went with a direct thread suppressor, which is half the weight of the previous supressor… It just doesn’t add up. I don’t think there’s any elevation built into my rail, I think 20 MOA built into my Spuhr

Post some pictures if your worried about damage. Otherwise it's a shoot in the dark guessing.

Ant time you add or remove weight on the muzzle you can expect some poi shifting. Completely normal, although sounds like you torqued the hell out of your bedding. I would suggest pulling your barreled action and putting it back in just to make sure it isn't twisted.

I would expect a poi shift when changing muzzle devices. Sometimes its worse than others.

How did you hold the rifle to turn it? Brake was held tight but how did you wrench on it?

I twisted the rifle which was fucking stupid,

I held on the stock and scope. It was tight but not obnoxious . If I can’t get it dialed in today at the range I’ll call Short action customs Monday

I wouldn’t be worried at all. I doubt you damaged anything. You changed the harmonics a good bit. Rezero and shoot it. Just adjust your zero stop.

Headed to the range shortly I’ll update you, question. If there’s no more downward adjustment on the scope because of the zero stop, what is the solution for that?

 

[supercorndogs]

With an integral zero stop scope, you loosen the turret put in the elevation you need, tighten it and turn it back to zero. Or you can slip it farther and zero, then zero your turret.

The rifles actually shooting 6 inches high right now and the zero stop is already bottomed out. I can’t dial down anymore …So I’m gonna have to play with things to see if I can get it dialed back in,

 

[Mulepackhunter]

Ya probably not a damage issue but maybe loosen your action screws and retorque them. It’s a bit of a large move in impact but to be expected.

There is. That scope has 130 moa or 38 mils of elevation and no way you bottomed it out with a 20 moa mount even if you have 20 moa in the rail, which you probably do. Also I don’t see a Spuhr mount in that pic. Just a Seekins and ARC. You just need to adjust the scope.

My bad, the SAC rifle actually has rings on it. My Tika is the one with the Spuhr not shown in the picture
So when I remove the turret, loosen the four screws there’s really nowhere else to go as far as “dialing down“ the zero stop mechanism is bottomed out, I realize I have tons of elevation available, but I need to go the other direction

 

[Cheeseburger1976]

Side note ……And that Seekins 7PRC in the photo (which I just got) shoot absolutely lights out for a factory rifle. Only downside is that skinny barrel heats up pretty quick.

Elevation doesn’t go one way. It’s the total available. If you had it on a flat base and no moa in the mount then it would be 65 moa up and 65 moa down. You just need to dial down and rezero. Read the direction on how to use your scope and set the zero stop.

Something is wrong. No muzzle device will induce that much shift unless you are getting muzzle strikes. Take the entire gun apart and put it back together, retorque everything. Scope, rings, bottom metal, action , barrel, muzzle device. Ensure everything is correct. My guess is either muzzle strike or something is loose in there.

 

[Cheeseburger1976]

Bottomed out at zero stop. So if it’s still shooting 6” high, not sure how I can possibly dial down more.

[Rob01]

Also what did the group look like at 6” high?

 

[Cheeseburger1976]

Read the directions.

Got it . I’m an idiot . And was totally overthinking it .

Headed to the range shortly to make the adjustments and check groupings.
Yesterday I ran out of time to really get things figured out, so I will shortly after I drop my boy off at work

Yes, this ^^ was not a good idea. After getting your zero fixed, if the groups are opening up at all then try re-seating your action and re-torquing your action screws. Just a suggestion. I doesn't take much loosening to cause problems.

P.S. - Actually, I'd re-seat and re-torque in any case....using your rifle as a breaker bar...well, better safe than sorry, righ?

 

[Cheeseburger1976]

Well, the verdict is in. Luckily I didn’t do any damage, I got her dialed in. Readjusted the zero stop and she’s good to go.

 

[pabrousseau]

Just because it's lighter doesn't mean it's going to impact higher.
