Semi-auto, 160 ft-lb... one of, if not the most powerful semi airgun in the world. Comes with the removable carbon back tank, 5 10 rnd cnc mags, Vortex 2-7 scope, Donny FL Ronin modular silencer, and about 1,000 pellets. Also have a hpa 12/120v pump which is great for mobile recharging I can sell you for extra at a good price. Scary fun for an airgun, pretty dang accurate too.
