I asked this over five years ago, but never got an answer, so I’ll bump it up and ask again. Can some M&P10 owners throw a pair of calipers or something on the barrel and tell be the approximate OD? I don’t care about flash hider OD’s or thread diameters. I’m just curious about the diameter of the barrel.
In the pictures the 811308 and the 11532 appear to be different barrel diameters?? And why is there a $400-$500 difference in those? The only difference I see is a 18” vs. 20” barrel.
