B3-1 pellet rifle power spacer/shim
cults3d
This spacer/Shim is designed to fit into a standard B3 pellet rifle and add significantly more power to it I don't own a chronograph but my best guess is that this spacer adds at least 100 FPS. I have tested this part on a B3-1 with good results I'm certain this part will work on the B3 -2 and the B3 -3. It's a bit of a pain to install but once it's in it works like a charm. I'd recommend using either a very long clamp or just an extra set of hands if you're not sure how to install it just refer to the pictures or look up a video on YouTube on how to disassemble a B3 pellet rifle. Hope you enjoy
