Hellraiser HellBoy CO2 BB Tactical Rifle

Availability: In Stock

Unload a firestorm of BB fire with the Air Venturi Hellraiser HellBoy! This CO2 powered air rifle is a realistic replica of the iconic M4 carbine AR. The construction features almost entirely metal parts, including the receiver, barrel, and full-sized drop out magazine. Just like the real steel rifle, the HellBoy has a removable carry handle that hides a Picatinny optics rail, and the handguard can be upgraded with extra tactical rails. The textured pistol grip, six-position crane stock, and integrated swivel sling mounts provide a comfortable setup. It can unleash 18 rounds in semi-auto at speeds up to 500 FPS!

HellBoy M4

I have had my HellBoy M4 since they were first available in North America, and I also bought a spare magazine. I added rails to the hand guard for a light and a vertical foregrip. I wish the pistol grip was AR compatible. While I had the gun field stripped, somehow the charging handle came out and the spring was stretched so much that it doesn't work properly. It isn't that important, since it just simulated the charging handle action, and doesn't actually do anything for the gun to function. Even still, I would like everything to work properly. I have found the two magazines I have shoot at different power levels. The one that came with the gun was tested and averaged around 500 fps, but the spare magazine averaged much lower, around 425 fps. The fire selector switch has become very loose, and unless I can figure out how to tighten it up, I expect that it will fall off the gun eventually. Despite the couple of criticisms, I still enjoy handling and shooting this M4 replica.

I got this rifle 6 months ago, it has some issues I found... the safety lock broke, the CO2 leaks when i put a new one in, ammo stuck in the barrel recently.
