Shoulder fired low velocity grenade launcher: a wide smooth bore over a boxy receiver, a quadrant leaf sight on the rail, a six round box magazine of practice rounds, a slotted handguard and a folding wire stock. Dimensions 0.15 by 0.29 by 0.69 m (X by Y by Z). Metre units, +Y up, +Z front; the origin sits on the ground at the footprint centre unless stated otherwise. Wind blown snow, packed track snow, blue glacier ice, dark teal and safety orange station cladding, off white insulated panel, galvanised steel, gunmetal, black polymer, white and grey and teal cold weather cloth, warm window glow and cold blue marker light. Rigid node-transform clips magazine-open, magazine-close, bolt-open, bolt-close drive the named parts on their own pivots. There is no skinning and no skeleton; every other surface is static. Original invented archetype: it copies no real firearm and carries no maker, model or product name, and no markings, logos or lettering. The bore is a modelled recess and fires nothing; there is no muzzle flash, projectile, recoil, ammunition count or damage data. The magazine, the action and the stock or bipod where fitted are the only moving parts; the barrel, the handguard, the sights and the sling loops are static. It stands at y = 0 on the parts it would really rest on.
