Jun 14, 2009. 10:50 AMpls (author) says:

Yeah, I just used it because it was spay painted so I didn't care about sharpening it, so then I used it for my ammo.

Dec 22, 2011. 12:53 PMslifenoa286 says:

I'm about halfway through building it right now, having trouble deciphering the improved trigger. As a side note, building with k'nex destroys my hands...
