Well, I got my gas block changed, the Holosight on and the BUIS. Almost. The BUIS I bought from Sportsmans Guide for about $50 each. (I know, I am cheap. It about killed me to pay that much!) These sights are made by ProMag, so probably made in flipping China, although I can't find a mark on them anywhere as to country of origin. The rear sights mounting screw was actually bent when I got it and is not long enough to mount it, so it is just laying on the flat top in the picture, but I couldn't wait to show it off. SG is sending me another screw. I have not sighted the Holosight in yet as I figured I would wait until I get the screw and sight them both in at the same time. (That and it is deer season here.) Anyway, here is the not so great pictues. I will take some of the other side when I get my screw and the sight will stay on!!!!
