What would happen.....

Be careful if you are not sure it aligns with the barrel , hopefully you have the clearance. Have at least a machinist look at it.

What would happen is something you wouldn't want to experience

I have a neighbor who received an 458 upper from RRA that was threaded so off center from the bore the bullet actually would have struck the installed factory installed muzzle brake.

And you should have seen the chamber to barrel alisgnment on that Jewel!! Obviously quality has taken a dive during the shortages of the last year.

Rifle fired flawlessly.
Mosin was really fun to fire and I could fire it all day long.

I put a no name comp/flashider on my Ruger gunsite .308. I hated the stock one and this one looked way Ninja After 500 rounds in one afternoon, in the desert, the muzzle blast/heat swelled the "bird cage part" and started to crack it. At one point my POA went to *****e and thats when I noticed the damaged flash hider. I stopped after that and reinstalled the ugly Ruger unit (Barf!)
