Did I bend the barrel or action??

[lte82]

Long story short, I tried to take the muzzle brakes off of one of my AR's and a 338 lapua, in the field, with a wrench and a lot of torque and they both immediately lost their zeros. The AR was about 4-5 moa low and left, and the 338 was about 1 1/2 moa low. Prior to this, they were both shooting perfect POA to POI.

Did I bend the barrels or upper receiver or action?

I realize I should have used a barrel vice at the muzzle, but figured I could macgyver it with no problems. Did I just really screw this up?

Installing a muzzle brake can shift your POI, particularly if torqued too tight. Removing it will should it to the original zero, that probably what you're seeing.

Well thats the thing. I never actually got them off.

Sounds like you bent something. But if they're still holding groups you probably just need to re-zero.

How many times did you twist the barrel around? Check the twist in your barrel to see if it WAS 1 in 7" and now it is 1 in 9" you REALLY twisted the barrel a lot. Just kidding I doubt you did any permanent damage. Like SWThomas said re-zero them.

You need to use spell check.

Lol @ TP.

I took out the 338 lm tonight with 7 rounds since thats all I had left. I put 4 in a 1/2 moa group at 100, went to 300 and put the last three in a .3x moa group. Yea, it still shoots. Im guessing my ar will do thr same thing. I still would love to know what exactly I "bent".

Guess that would be "Gain untwist rifling".
