Are the spacers at the bottom rod neccessary? Or are they just there to keep the other two rods from getting too close to each other?

If you guys want people to take any of the knex posts seriously, I suggest you act a little more mature, or at least take it to your own instructable.

Semi-automatic guns are guns that shoot every time you pull the trigger -- not guns that load bullets every time you pull back the firing pin, which are bolt-action or pump/pullback guns. The way this gun's trigger system is, it looks like a pullback. I am not criticizing the gun (most pullbacks are actually more powerful than semi-auto), but will someone who has built it tell me if it i a genuine semi-auto? I am looking for a compact gun that is or is a fully-auto, and if someone finds one, please PM me.

DJ Radio says:

You are correct, but this gun was made/posted before Oodalumps came and clarified the knex definition of semi auto.

Jan 2, 2010. 7:27 PMBartboy says:

Semi auto is semi auto, it doesn't matter what you're talking about.

Jan 2, 2010. 8:47 PM

DJ Radio says:

Yeah, but I'm saying that (your name here) called it a semi auto BEFORE we had clarification on the subject.

Jan 21, 2009. 12:50 PM(your name here) (author) says:

"Or bolt-action, pump-action, or whatever you want to call it. (it loads automatically)" Yes, technically, it's not a semi-automatic. As far a knex goes, however, you're probably not going to find any semi-automatic or automatic with decent power, much less a compact one. (in my opinion, power is a must-have.) Also: the more compact prototypes I have made involve permanently "modifying" some knex pieces.
