3D Modelling: Kinetic Blaster

This is an idea for a sci-fi weapon that I had after looking at a clamp. The Kinetic Blaster charges when the user pulls out the head of the blaster. That kinetic energy charges the weapon's energy cells. The weapon has a few shots in it before it needs to be recharged with another pull. Textures from 3dtextures.me, HDRI from Polyhaven.
