[QUOTE="LanceS4803, post: 5179221, member: 9491"] Well, no new good info. From a poster on arfcom who looked at the mil spec drawings, the regular AR sight base hole is .1805" tolerance +/- .001 Gas tube diameter is .180", +/- .0006 Using gauge rods, the gas block hole is .1785 Caliper on the gas tube is a very consistent .178 The fit is incredibly tight, as might be expected. Viewing through a bore camera didn't reveal any internal defects in the block. I'm out of ideas. Don't really want to start taking apart other rifles, pulling flash hiders, etc. to put them on this barrel and then reverse everything. BTW, a Hanson profile barrel is slightly thicker full length, without being overly heavy. [/QUOTE]
