    I saw this today first in a facebook ad. I was sure it had to be a joke trying to reel me in to get a nice computer virus, so then I google searched it. Sure enough-this is a real thing!! I can't imagine why you would want to put so many weak spots on the one part of the gun that takes the most stress. To me-it's like drilling the crap out of your frame rails of any diesel truck.

    Does anyone have one of these, had one of these, or know of how they perform? It really just seems like a show piece to go with one of those skeleton lowers.

    It looks like a custom competition piece. I am going to assume your rifle and ammo have to be tuned to run properly with it.

    It reminds me of custom race guns with their slides lightened.

    I saw where a guy did his entire AR this way using various sized hole saws and drill bits a few weeks ago. Was ugly as hell but weighed in lighter than I'd ever seen one weigh before.

    EDIT: Not the one I was looking for but found some pics of the idea. This guy could really use one of those BCGs.

    I wonder if it cycles properly with standard springs and ammo?
    Looks like it'd require some tuning.

    Round holes can effectively lighten the piece without affecting the strength. It only works with round holes though because the stress is evenly distributed around the hole. A square hole, for example, will have high stress in the corners. Of course, there is a point where you remove to much material and it weakens it too much. On the bolt carrier, I'd be worried about loosing too much mass.

    I wonder if that thing whistles when the operator is operating.

    I too wonder how that would cycle. AR pistols don't like light carriers or buffers. They TEND to cycle better with the FA carrier and/or a heavy buffer.

    On top of all that, it kidna looks like poo.

    higher mass helps slow the cycle rate and reduce stress on your gun. Lower weight bcg=higher stresses. This part is probably just for those 3gun ars with rifle length adjustable gas blocks. Longer gas systems slow the cycle rate and require lighter buffers.
    I didn't build an ar cool enough for one of these
