An anti materiel rifle, the longest and heaviest weapon in the pack: a metre of heavy barrel inside a quad rail, a fist sized two chamber muzzle brake, a carry handle over the receiver, a monopod under the toe and a wide bipod on the receiver front. Dimensions 0.127 x 0.392 x 1.780 m (X x Y x Z). Origin at the footprint centre, resting on y = 0; metre units, +Y up, muzzle and point toward +Z. Named pivots: magazine at (-0.0067, 0.2316, -0.3898); bolt at (-0.0067, 0.3236, -0.2098); leg-l at (-0.0187, 0.236, 0.1102); leg-r at (0.0053, 0.236, 0.1102). Connectors: optic optic-rail at (-0.0067, 0.3495, -0.1749) facing +Y; muzzle muzzle at (-0.0067, 0.29, 0.8901) facing +Z; magazine magazine at (-0.0067, 0.2316, -0.3898) facing -Y; underbarrel underbarrel at (-0.0067, 0.2423, 0.1401) facing -Y. The trigger linkage, the gas system, the extractor, the feed pawls and any belt run are modelled as solids and left static: a rigid node transform cannot drive a linkage honestly, and faking one costs a consumer more than it gives. Rigid node-transform clips magazine-open, magazine-close, bolt-open, bolt-close, bipod-open, bipod-close drive named nodes on their own pivots. No skinning and no skeleton. Blued gunmetal, bright machined steel, dark anodised alloy, black and dark earth polymer, rubber, walnut, brass, copper, leather, olive paint, optical glass, concrete and emissive red, green and warm white for reticles, lasers, tritium and lamps. Physically based flat colours with no texture maps. Original invented design: no real make, model, manufacturer or marking is represented. Free 3D model for Unity, Godot, Unreal, three.js and Blender. No collision or navigation data.
