I finally got all the paperwork taken care of, and here she is. Its a 9.5" barrel and a 8.25" suppressor, so thats just at a normal 16" upper w' FH. I have shot subsonics before, but they are going faster with the back pressure. Lots of fun tinkering with loads coming up. I have only shot it once since I got it... need to get to the range again...
