Inconsistent measurement tolerances - Rainier Arms Match Series MK12 SPR .223 Wylde SPR AR-15 Threaded Barrel

I bought 2 of these. There were 2 different versions. The markings on one is laser engraved, while the other one was mill engraved. Both have the dimples for a set screw to secure a low profile gas block. Also both have the same quality, texture, color. The only issue is one of them had 0.001 or 0.002 wider diameter (the portion of the barrel where the gas block sits). So, in one barrel, my Badger Ordnance gas block just sits perfectly in, while the other one, I have to force in. Simple solution would be to lube the barrel or grind the gasblock a little on its inside diameter. On the plus side, those who prefer a tight gas seal, this is for them.
