Based on the ultimate warfighter rifle, the M4 Carbine, incinerate targets with blistering semi-auto shots and a real steel feel fueled by a single CO2 cartridge.  Able to send .177 BBs downrange at over 495 fps, the HellBoy features full-metal construction throughout the barrel, receiver, and the 18rd BB magazine.

Use the included open flip-up sights or remove the rear sights to expose a 5.5” Weaver/Picatinny rail.  Each of these airguns is field-strippable just like a real M4, and each includes integrated swivel studs for easy carrying options. Its adjustable rear stock can be set to your preferred pull with a press of a button.
