Light machine-gun systems · 5.56×45 mm NATO

AIA-LMG-5.56×45-Mk1-[BL]

A modular, gas-operated light machine-gun system in 5.56×45 mm NATO. The current AIA-listed configuration has a 406 mm (16 in) barrel and left-side belt feed. The broader 5.56 mm model range also includes a 460 mm (18 in) standard-length version, 330 mm (13 in) compact versions and a dedicated compact NATO-magazine configuration.

The system uses a long-stroke gas piston and open-bolt operation. Model-dependent features include semi-automatic and automatic firing modes, belt, drum or magazine feed, folding or telescopic stocks, adjustable cheek rests, bipods and sighting equipment. Dimensions, weight and performance figures are listed by configuration below.

5.56×45 mm model variants

The 16-inch entry reflects the current AIA listing. Other rows reflect distinct brochure-listed models. The brochure identifies the compact magazine-fed model separately; it does not publish separate weight or length figures for that version.

Operating system and firing modes

Gas operation

Long-stroke piston

Gas-operated, long-stroke piston architecture with open-bolt operation. The current AIA specification additionally lists a rotating-bolt locking system.

Firing modes

Semi-automatic and automatic

Brochure-listed models provide semi-automatic fire for controlled engagement and automatic fire. The current AIA-listed configuration specifies safe and fully automatic settings; confirm the fire-control option for the selected model.

Gas regulator

Environmental settings

A gas regulator supports continued operation in adverse conditions. Regulator settings and applicable operating instructions are model-specific.

Safety and servicing

Field-maintainable layout

The documented features include multiple safety mechanisms and quick field disassembly for maintenance.

Configuration options and accessories

Feed configurations

Belt, drum and magazine

The current AIA listing specifies left-side belt feed with 50-, 100- or 200-round containers. Brochure-listed 5.56 models include 150/200-round drums and a dedicated NATO-magazine version. The 7.62 NG-7 drum options are listed at 100/125 rounds. Availability is model-specific.

Stock and cheek rest

Adjustable fit options

Stock options include telescopic, folding and telescopic/folding versions. The current AIA listing specifies a five-position telescopic stock and a three-position cheek rest; other models offer an adjustable cheek rest and length of pull.

Bipod and platform mounts

Support and mounting

A folding bipod is listed; the current AIA version has three height positions. Brochure-listed mounts include airborne, vehicle and naval installations. Mounting compatibility depends on the selected model.

Sights and rails

Optics-ready configurations

Picatinny rails support optics and accessories. Back-up iron sights and tritium night sights are listed options. Selected configurations can be fired with the stock folded.

Muzzle and accessory options

Configuration-dependent equipment

Listed accessories include an assault grip, blank-firing attachment, muzzle devices and suppressors. The current AIA listing specifies an A2 birdcage device and M15×1 muzzle thread.

Environmental qualification

Variant-specific documentation

The brochure references MIL-SPEC 810 environmental requirements. Applicable test basis and qualification should be confirmed for the exact model and configuration.

Performance data by configuration

CONFIGURATIONPUBLISHED FIGURES
Current AIA-listed 16-inch model750–950 rounds/min; muzzle velocity 900 m/s; 600 m point-target range / 800 m area-target range; 529 mm sight radius; 35–70 N trigger pull.
5.56 mm brochure-listed modelsApprox. 850–1,050 rounds/min with magazine or belt; approx. 950–1,150 rounds/min with belt in extreme conditions.
7.62 mm compact LMGApprox. 600–750 rounds/min, positions 1 and 2.
7.62 mm ultra-light modelsApprox. 600–800 rounds/min, positions 1 and 2.

Cyclic rate, muzzle velocity and range depend on model, feed system and operating conditions. The current AIA-listed data and brochure-listed model data are kept separate.
