modern assault rifle 3d model

A highly detailed M4 carbine rifle inspired by Call of Duty weapon blueprints. Dark tactical color scheme: matte black cerakote finish on the receiver and barrel, dark grey polymer stock and handguard. The handguard features integrated glowing cyan blue LED light strips that pulse faintly, visible through hexagonal cutouts. A futuristic holographic sight is mounted on the Picatinny rail, projecting a bright blue reticle with targeting data. A small digital screen on the left side of the magwell displays glowing green ammo counter numbers. The barrel has a flash hider and heat shield with subtle heat stain effects. The bolt catch, charging handle, and fire selector are metallic with slight wear. The magazine is dark grey with visible cartridges through a small window. High-resolution PBR textures with realistic metal, polymer, and glass shaders. Subtle scratches and dirt in crevices for realism. Game-ready, optimized for first-person view, FBX export.
