This was built on a 1968 Iszmash Parts kit with a Green Mountain barrel. It has an ultimak front rail and US Palm Grip. Built by Mesa Kinetic Research in Louisiana. Looking for $1500 obo shipped to your ffl. Between zero and ten rounds through it. I can't remember if I ever fired it, but if I did, it wasn't much. Will include at least two magazines. More if I have more.
