Decided to get this Wolf T91 AR upper, upon recommendation for review "from a homestead defense" POV.

I had a Heck of a time getting UPS to deliver it to me "new Federal rules" they claim as the excuse, but that's for another video.
I put 120 rounds down range before making this video, and had issues with the brass getting stuck in the chamber.
consulted my good friends at RD guns in Copperas Cove, and we came up with a plan of things to try.

More tests to come in another video. It took a whole video to get to where I am I in the first phase of testing!
