Not quite a premium August 20, 2019
Reviewer: John from PA  
Machining on the carrier is pretty rough. Lots of tool chatter marks and small burrs. Firing pin retaining pin was harder to remove and install than any of the other two dozen bcg's I have. Staking is excellent and the bolt seems well made but the rest of the carrier looks like it should be a second.

Reviewer: They call me bacon from WV United States  
I ordered this bolt carrier group on 4/26 and got it 4/29. My initial thoughts are It is .13 ounces heavier than some of my other boltcarrier groups, the gas key is staked properly, the finish is darker and deep, it locks up fine, the headspace was perfect, it cycles and functions flawlessly. After degreasing and lubricating with my lube of choice I took it to my backyard range and ran a few rounds through it and came to the conclusion that it still needs a few more rounds ran through it to break it in. For the price... it's a bargain, the shipping was fast, the quality is there. So I can honestly say that I would recommend this to a friend and I would suggest it to whom ever is reading this and I'd hope you would do the same.
