This is version 2. It uses a fair amount of pieces.

Bullet holder to make it shoot farther
Accurate iron sights
35-40 feet range with two 64# RB's
More power than the 1st version
You can put as many bands as you want onto the ram but it will be really hard to pull back if you put more than 4 RB's on each side.

Small handle
Bullet spins out of control sometimes when shot
