HellBoy M4 CO₂ Air Rifle – Full Metal Semi-Auto BB Rifle
The Hellraiser HellBoy M4 CO₂ Air Rifle delivers realistic semi-automatic BB shooting in a rugged, full-metal tactical platform. Styled after the iconic M4 carbine, this air rifle combines strong build quality, fast-paced shooting, and authentic handling for an exciting backyard and range experience.
Powered by a single 12g CO₂ cartridge housed inside the magazine, the HellBoy fires 4.5mm steel BBs at speeds up to 495 FPS. This provides rapid follow-up shots and consistent performance, making it ideal for target practice and recreational shooting.
Realistic Full-Metal Tactical Construction
The HellBoy M4 features a durable full-metal receiver, barrel, and magazine, giving it a solid, realistic weight and feel. Only the retractable stock, pistol grip, and handguard use high-quality polymer to reduce overall weight while maintaining strength and comfort.
Because of this construction, the rifle offers excellent balance and a highly authentic shooting experience.
Semi-Auto Action & Easy CO₂ Loading
This semi-automatic BB rifle uses an 18-round magazine that also holds the 12g CO₂ capsule. Simply load the cartridge, fill the magazine with BBs, and you are ready to shoot. The efficient CO₂ system ensures smooth cycling and satisfying repeating shots with every trigger pull.
Adjustable Stock & Optics Ready
The adjustable rear stock allows you to customise the length of pull between 30″ and 33.5″ for a comfortable shooting position. In addition, the removable carry handle reveals a 5.5″ Weaver/Picatinny rail, making it easy to mount optics such as red-dot sights or scopes.
The rear sight is adjustable for windage and elevation and features two flip-up aperture settings for flexible target acquisition straight out of the box.
Field-Strippable & Practical Design
For added realism and maintenance convenience, the HellBoy M4 is field-strippable, just like its firearm counterpart. Integrated sling swivel mounts also allow easy attachment of a sling for comfortable carrying during extended shooting sessions.
Overall, the HellBoy M4 CO₂ Air Rifle offers impressive realism, solid construction, and fast semi-auto performance in a versatile tactical BB rifle platform.
