    Haven’t had a chance to finish this build and run it but fit and finish is perfect. I’d buy this again in a heartbeat. Pictures online seriously don’t do this upper justice. It is a sight to behold! Get one!

    Overall an excellent upper. Arrived fast. Well packaged. Unit was pristine, no scratches or tool marks.

    When assembled on a Ballistic Advantage lower, the fit was PERFECT. There was zero slop between the upper and lower receiver. I rated a 5 with two small caveats. The birdcage was only hand tight. No big deal but a small imperfection. I would have liked to have a nitride gas tube rather than stainless silver.
    The handguard is superb. It fits the had well with no need to hang a bunch of MLok fasteners since the rails are where you need them. Barrel is Ballistic Advantage which is top notch.

    Overall I highly recommend. Plus, BKF shipping is priced right.
