I have a Smith & Wesson M&P15 and I am looking to replace my handgaurd and (of course) replace the gas block.
I dont have a micrometer and cannot get an accurate diameter of its barrel.
Anyone know what the outside diameter of the barrel of the M&P15?
Thanks!

Almost every "standard" AR barrel is .750"

Unless you plan on keeping the front sight tower for some reason you could always just modify/chop off the tower and the bayonet lug and have a perfectly functioning pinned gas block. Your gas block journal should be as mentioned .750.
