7.62×51mm ROTARY-BARREL MACHINE GUN

CS/LM12

The CS/LM12 is a multi-barrel, externally-powered rotary machine gun chambered for the standard 7.62×51mm NATO cartridge. Developed for police/security and counter-unmanned aerial vehicle (C-UAV) missions, it is deployable across a wide range of platforms, including vehicles, helicopters, and naval vessels.

Building on the proven architecture of different classic rotary guns, the CS/LM12 incorporates a number of indigenous design improvements. An electric motor drives the barrel cluster, completing the automatic feeding, firing, extraction, and ejection cycle independently of propellant gas pressure. A flexible belt links the ammunition box to the feed mechanism, ensuring a safe and reliable continuous ammunition supply.

The weapon is fitted with an electronic fire-control system offering selectable firing modes and a real-time display of rate of fire, rounds fired, and remaining ammunition. Two cyclic rates are selectable via a rear-mounted control button — a low rate of 2,500 rpm and a high rate of 6,000 rpm. An integrated spent-case and link collector prevents ejected components.

KEY FEATURES

  1. NATO-Standard Calibre — Fires the widely available 7.62×51mm NATO cartridge, ensuring logistical compatibility with international forces.
  2. Dual-Rate Selectable Fire — Offers two cyclic rates — 2,500 rpm (low) and 6,000 rpm (high) — allowing the operator to match firepower to the tactical situation.
  3. External Electric Drive — Powered by an electric motor requiring ≤2.3 kW; barrel rotation and the automatic cycle are independent of propellant gas pressure, enhancing reliability.
  4. Large-Capacity Ammunition Feed — Standard supply is a 1,000-round belt box, with other capacities available on request, providing sustained firepower.
  5. Wide Firing Arcs — Elevation from −45° to +60° and traverse of ±180° (full 360° coverage) enable engagement of targets in virtually any direction.
  6. Exceptional Barrel Life — Each barrel is rated for ≥60,000 rounds, significantly reducing maintenance costs and downtime.
  7. Flexible Belt-Feed System — A compliant ammunition belt between the box and the gun ensures smooth, jam-resistant feeding at high cyclic rates.
  8. Integrated Fire-Control & Display — An electronic control unit with display shows real-time mode, rate, rounds fired, and remaining ammunition count.
  9. Multi-Platform Adaptability — Can be mounted on ground vehicles, naval mounts, and helicopters, meeting diverse operational requirements across land, sea, and air.
  10. Safety-Oriented Design — A collector for spent cases and disintegrating links prevents foreign-object debris that could endanger the platform or crew.
