Criterion hybrid contour 10.5 - Criterion Barrels AR-15 Hybrid Contour .223 Wylde Barrel

First impressions out of the box the barrel is very clean as for the gas block hole i think they very some come over gassed some come just right and probably a few undergassed mine the one i received seems a little over gassed but then again im running a yhm rb so thats could be the culprit as for function it runs flawless but overall i would recommend this to anyone looking at their first aftermarket barrel other then the market one's that come on literally 99% of the ar platform.
