I call it the Bullmastiff, its near brand new and professionally tuned and modified for power and hunting larger game, extended air tube. Stock Valve making 300 fpe with 150g slugs, no leaks. 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.
