I call it the Bullmastiff, its near brand new and professionally tuned and modified for power, extended air tube. Stock Valve making 300 fpe with 142g slugs, no leaks. I had this built for hunting. Comes with everything from the kit; Range bag, bipod, CP scope, and a bunch on Neilson Slugs. Mounted the scope, but never zeroed it, the only shots its taken were during the tuning process, asking $800 shipped conus + PP fees if using G+S. I also accept venmo, zelle, square cash, and google. Pics of the actual rifle upon request, below are shot strings and accuracy @ 100 yards. Text @ 4Four3-8Two0-8Two09, or email me on here.
