2026.03.01 New version update
1 Gantry structure and clearance optimized, solving the problem of the gantry not rebounding and reducing the difficulty of rubber band installation

3 Inner tube structure and clearance adjusted, now both sides can pull the bolt The front muzzle can install a bearing tube by itself The rear part is adapted for coiled light hardware
4 Magazine fine-tuned, adopting a new rubber band installation method to reduce the squeezing force on soft darts
5 Added basic sights and buttstock to improve comfort
6 Added hardware adaptation parts
The entire model is PETG printed, no hardware is needed, but the power source is a rubber band (Hardware adaptation parts have now been added)
The rubber band used is a 40mm diameter rubber band, and the soft darts are 13*36mm universal foam darts Compatible with Artisan Straight Dragon Claw magazines The hardware version picatinny rail uses M3*8 cylindrical head screws The bolt uses M3*20mm or longer cylindrical head screws The coiled part uses an outer diameter of 16mm, a wire diameter of 1.4mm, and a length of 140mm
The printed magazine, due to the characteristics of rubber bands, will have greater elasticity the longer it is pulled, making it easy to flatten the foam darts It is recommended to prioritize other creators' constant force spring version magazines
