I have had friends who have good experiences with BCA uppers, in 6.5Grendle, but they had rough chambers issues, with the SS or carbon steel barrels, I have purchased a few BCA right side charger uppers in .223whylde and 1 in 6.5GRR, I have not tested 3 of these uppers yet! I did notice my 6.5GRR 18'' HB SS has a blemish in the chamber it has a rough polishing or a not clean surface finish in a small part of the chamber, and I and I'm concerned about it! I can clean it up myself if need be, 1 of my 5.56nato 16'' uppers I have shot is very accurate and has no noticeable chamber blemishes at all, and runs flawless so I hope my other uppers do as well? But on the other side I can always replace the barrel if need be JMO!
