[ARCHIVED THREAD] - M&P10 Barrel Break-In?

Posted: 12/17/2014 9:52:07 PM EDT

I know the procedure for the proper break-in of a rifled barrel from my bolt guns. But is there the same need for a chromed lined barrel?
Thanks

Barrel break in is a myth depending who you talk to

Correction.....my barrel is not chromed lined and is 4140 steel. That 4140 steel makes proper barrel break-in all the more important

Where did you get that information? I read everything on S&W's web sight and all I could find that the barrel is not chromed lined and is made of 4140. That would be great if it is.

It has 5r rifling too...one of the nicest stock 7.62 AR barrels around.
