    smooth action

    i purchased this bcg to replace my new stock bcg because it would stick closed after a dry fire test every time.
    now keep in mind it is an exact duplicate of what i already had so i had no idea if this at3 bcg would rectify the
    problem. rcvd it a day ahead of schedule which was awesome. cleaned and lubed and installed and tested and
    it runs flawlessly. at3 and toolcraft will be getting more of my business . im from reno so bet on it.

    Thank you for the feedback, Guy. We're proud of our BCGs and we're glad we could solve a problem for you.

    Bolt jams

    Bolt gets jammed easily Multiple times with many different types of ammo and clips made of metal and plastic. Had to use a small hammer on the driver to retract bolt. Oiled it well before using it and it appeared to move easily but when ammo placed it jammed forward and would not push bullet into chamber fully.
