New from Hellraiser, the HellBoy, provides satisfying repeating shots fueled by a single 12-gram CO2 cartridge. Based on one of the greatest weapons platforms ever created--the M4 Carbine--heat up the range with blistering semi-auto shots and unparalleled realism for a tactical experience like nothing on Earth!  

Each HellBoy features a full-metal construction throughout the barrel, receiver, and the 18rd  BB magazine.  Load up a single 12-gram CO2 and start sending BBs downrange at speeds up to 495 fps.  Just like the real M4, the HellBoy gives you a lot of choices for your optics. Shoot straight out of the box with included open sights or remove the rear sights to expose the 5.5" Picatinny/Weaver Rail--ideal for a small scope or red-dot sight.  Its adjustable rear stock can be set to your preferred pull length with the press of a button. Each HellBoy is field-strippable, and includes integrated sling swivels for easy carrying options.

If you want a truly thrilling backyard shooting experience, choose the HellBoy and incinerate your targets.
