rexdino5 (author)2010-06-06

Can I use a small blue one-way connector instead of the tan one-way connectors on all the steps? Since I have very little tan pieces but alot of the one-way blue connectors that are just like the tan ones.

rexdino5 (author)rexdino52010-06-06

Also does anybody know how to make a safety for any gun? Since one time I made a crossbow and it went off by accident and hit my mom in the glasses... I don't want that to happen with the gun. I always point the gun down to the ground with two hands when I'm not using it but I still my go off by accident.

~Aeronous~ (author)2010-03-02

 hahalolz nice pun. BTW how old are you? cos you always act 100 percent mature and talk as if youre IQ is 300. its annoying me. (not you, me imagining a young boy as smart as you.)

Oblivitus (author)~Aeronous~2010-03-03

Haha, thanks, you're the first one to comment on my pun (it's on the Z35 instructable too). I'm 18.

Ps2playa (author)2010-01-20

looks like a gun that if you got shot with it you would bleed to death

Oblivitus (author)Ps2playa2010-01-20

Lol, it has half the range of a powerful pin gun, so not really, but it is powerful for a shotgun.

Ps2playa (author)Oblivitus2010-01-20

oh man i hate it that i was kinda wrong

redrover95 (author)2009-12-15

that was funny about the male and female

Dr.Squirrel (author)redrover952009-12-21

Which is Which?

J Moneyman (author)Dr.Squirrel2010-01-17

if ur talkin about the hinges, just get 2 sets of hing connectors.

J Moneyman (author)Dr.Squirrel2010-01-17

male has the round thing on the end, female has the valley groove that the male connector clips into. go ahead, laugh it up!

Dr.Squirrel (author)2009-11-08

Hey, you have a parts list?

Oblivitus (author)Dr.Squirrel2009-11-08

builder968 (author)mhihihhi2009-11-25

 No offense, but t would help the people on Instructables a lot if you could use English, mainly, because some people don't know french (I know a little). Sil vou plait?Merci beaucomp. 

mhihihhi (author)builder9682009-12-08

oh,ok... ill stop using french as much.

mettaurlover (author)2009-12-01

i made a massivly more compact version of this a while back, with the barrels oriented vertically and a much smaller trigger system. only problem was that the ram jammed frequently when cocking unless you held down the trigger.

narutokid201 (author)2009-11-22
