A steampunk-style mechanical 3D wooden puzzle replica modeled after the classic 1950s pump-action shotgun. 
It features a functional, spring-loaded sliding fore-end and a safe rubber band firing system.
The model replicates real shotgun mechanics. It features a slidable pump-action fore-end to load ammunition, a spring-driven bolt simulation, an integrated rear sight for alignment, and a real-action trigger.
The internal mechanism holds a total capacity of 5 rounds and launches 2 rubber bands simultaneously per trigger pull ("one shot, two bullets"). It features an effective shooting range of approximately 5 to 8 meters.
Built using eco-friendly northern cold-zone basswood plywood sheets, the 170 pieces utilize high-precision laser-cutting and mortise-and-tenon interlocking joints for a gap-free setup out of the box.
Due to standard international shipping protocols, the package typically excludes structural gear wax. You should have a standard household paraffin candle or crayon ready during the build to lubricate the internal mechanical pathways.
