It fires pretty well, but it is hard to place rubber bands as there is no peg to rest them on. I've gotten it to work, though, and if you want instructions, please ask, and I'll be happy to post them. As a warning, though, the firing pin was very 'touchy.' If you bumped the firing pin upwards or the bands came out of place, it would fly upwards and try and slam through the gun. Eventually, after the right banding, that'll stop, but it's something to consider before asking for instructions, I guess. :3
It had: (I dismantled it to work on a turret pistol, but fear not, I can build from the pictures and from my memory)
A comfortable handle.
Sights. (sort of)
A trigger guard.
A very nice trigger.
About a 50 foot range before I dismantled it. (I told red thirty-five, but since then, I added another band and it went fifty feet.)
