A short gas operated carbine of original design: a machined upper and lower with a folding tube stock, a handguard with four vent slots, a stubby suppressor, a reflex sight with a lit red dot, a detachable box magazine that drops out of its well and a charging handle and bolt that run back along the bore. Dimensions 0.13 × 0.37 × 0.84 m (X × Y × Z). Metre units, +Y up, +Z front; origin on the ground at the footprint centre unless stated. Damp conifer forest realism: wet concrete and corroded corrugated steel, weathered pine, dark bark and soil, deep needle green, olive canvas, gunmetal and machined steel, with five emissive colours (amber fire, white floodlight, green status, blue screen, red warning) that also form the loot rarity ladder. Rigid node-transform clips magazine-open, magazine-close, bolt-open, bolt-close turn named nodes on their own pivots. No skinning, no skeleton, no skin weighting, no collision or navigation data. The trigger, the safety and the folding hinge are modelled but static; only the magazine and the bolt move.
