A cheap and structurally simple working proof-of-concept designed to test the viability of a fully 3D-printed slide and straight blowback ejection mechanisms.
A practical, lightweight structural evolution designed to incorporate metal inserts into a highly compact frame. Weighing under 200 grams, it features a shallow grip angle optimized to fit small 3D printer beds. It pairs a 3D-printed PLA frame with a robust steel barrel liner and breechblock to handle high-stress components .
