    AWESOME barrel..beats BA as far as attention to detail. I am very impressed with the fit and finish, and the gas block pin ensures that sucker isnt coming loose. A+++!

    barrel looks nice, haven’t finished build yet so can’t comment on accuracy yet

    Ok, you ready for this?
    Just finished my build after 3 years after autistic levels of research, purchasing and assembling parts.

    Hard to find a 1:7 twist 10.5″ barrel for some reason. 1:8 twist is questionable for stability of subsonic loads and suppressors FYI. Cost was not an issue/concern with my build, as it will be an SBR in a family trust with Geissele parts and Aimpoint Micro H-1 on a Larue LT660 mount (1.64″ to center of bore fyi). I decided just out of sheer curiosity to give this barrel a try thanks to ageuchi9’s review above. He wasn’t kidding, REALLY nice barrel and quality is immediately apparent from finish to machining.

    Range Results:
    Just got back from the indoor range for initial function test, and 100% flawless performance, and completely satisfactory accuracy. It shoots better than I can with a red dot, that’s for sure.

    Optic Zero info:
    I zero’d the Aimpoint H-1 to be 1.3″ low at 25 yards. According to Hornady ballistic calculator this gives best POA results up to 130 yards with the load mentioned above.

    Load Data:
    I loaded my own supersonic loads (125gr Hornady SST, 18gr of H110, OAL 2.100).

    Bottom Line:
    Outstanding performance!!! Will perhaps update this review once I stretch out it’s legs to 50 yards. I would purchase this barrel or another BKF barrel in a heartbeat. The barrel profile was also attractive and well thought out, AND it is cross milled for a gas block pin. I just wish it was also dimpled for one or both of the set screws.

    GET THIS BARREL!!!!
