    Can't see any defects, tolerance tight, no roll pins, all screw-in. Great bargain.

    AR15 upper receiver

    Posted by Peter on 25th Mar 2024

    Great looking upper. Very nice touch is an Allen head threaded pin to retain the forward assist for the BCG. No rollpin punch needed. Only problem is the exterior profile that required some modification to my Brownells upper receiver vise block. The angular side profile won’t allow the tool to close properly.
