Ok so I like the rifle but live on the wrong side of the world to send things in and out of the U.S. Without silly amounts of paper work...
So I just removed the deformed part of the barrel and suppressed it.
Hey guys firstly I love the M&P line up of guns.
Got this M&P 10 recently and really struggling with a lack of accuracy.
Tried everything ...
Then looked at the bore...
Please advise...
These lumps sit proud and seem to be caused by the punch that marked the outside of the bore?
