Full-Auto Lower + My Upper = Awesomeness

At the Bidet Shoot, we decided to take the upper from my 12-pound AR and put it on Mr. Cook’s Full-Auto AR Lower.

The biggest thing I noticed is that the PRI Gas Buster didn’t seem like it could keep up with the rate of fire. You can actually see me close my eyes during one of the bursts because the gas was getting to me. It works great for semi-auto, so I’d buy it again.

    The two suggestions I’ve seen regarding gas venting around the charging handle are to put silicone on the charging handle where it mates with the upper, and to install a gas vent in place of the forward assist.

    Personally, I’d try the silicone trick, as well as newer suppressor designs that minimize back pressure, before I removed a functional piece of my upper.

    Is that an actual suppressor or just a fancy flash hider? Because if it’s the former, that’s likely the cause of the gas in your face.

    It’s a real can. The gasbuster is supposed to mitigate that, and it works really well in semi.
