pls (author)ferrari4842009-06-12

Wouldn't work because the ammo cant fit inside the rail.

Killer~SafeCracker (author)pls2009-06-12

What did you do, spray paint the red rod??

pls (author)Killer~SafeCracker2009-06-13

Ya, a longgggggg time ago.

Annix15 (author)Blackbird172011-12-07

Blackbird17 (author)Annix152012-01-22

O_O

Killer~SafeCracker (author)pls2009-06-14

Wouldn’t that cause more friction??

yes but barely, unless he used spraypaint designed for plastics...

not if you use very good spray paints

pls (author)Killer~SafeCracker2009-06-14

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.

no its a tan rod wich is a reinforced red rod

H1T4TCH1 (author)sprout_less2010-08-23

deadaccount (author)2011-12-22

This makes me want to make it just for the looks. I would make it to shoot, but all my rubber bands are tiny.

Xzen21 (author)2011-02-21

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...
