Co2 M4 Full Auto .177 Caliber 4.5mm Steel BB Gun Air Rifle - Umarex Airguns Co2 Powered BB Carbine

May I present the Umarex Steel Strike — a full-automatic, M4-style .177 caliber CO₂-powered BB rifle crafted for speed, aggression, and controlled chaos. Wrapped in black polymer with a six-position adjustable stock, this isn’t for casual plinking — it’s for urban warfare in a world made of plywood and bad intentions.

Caliber: .177 steel BB — compact, fast, and lethal enough in the right hands.

Powerplant: Dual 12g CO₂ cartridge system — extended runtime, uninterrupted mayhem.

Rate of Fire: Full-auto and semi-auto modes — your finger chooses the sentence length.

Velocity: Up to 400 FPS — fast enough to sting, precise enough to end games.

Magazine: 900-round reservoir with a 30-round spring-fed internal mag — feed it once, fight all day.

Stock: Adjustable 6-position tactical — fit to your shoulder, or your mood.

Rails: Picatinny top and bottom — accessorize with light, laser, red dot, or all of the above.

Controls: M4-style ergonomics — familiar, fierce, and field-ready.

The Steel Strike is not for everyone. It’s for the operator who values volume over negotiation — the kind of shooter who clears a hallway without raising his voice.

Because some conversations are best held at 400 feet per second… repeatedly
