RK-1L airsoft spring grenade

Açıklama

Hi! Here is my RK-1L design. It is an airsoft spring grenade that uses an AEG spring and can be loaded with bbs. The grenade uses two pistons, which launch the bbs on impact from two separate chambers. Each chamber can hold up to 140bbs(I recommend loading about 80bbs). The impact sensitivity can be adjusted by a screw on the side. Both pistons have positioning pins and holes, which ensures that both pistons will open on impact. This design was tested with M120 spring. Using stronger spring may damage the mechanism. Parts list: Screws: - M6 nut - M4x12mm - M4x8mm headless screw (2pcs) - M4 nut (18pcs) - M3x12mm (6pcs) - M3x6mm headless screw - M3 nut (6pcs) Other: - M120 AEG spring - M6x75mm threaded rod - M4x125mm threaded rod (3pcs) - M4x60mm threaded rod (6pcs) - M4x16mm threaded rod (6pcs) - ∅2x15mm rod (3pcs) - key ring You get all STL files.
