cool, but isn't that a nerf reflex?

nerfrocketeer (author)Kona-chan2013-05-11

Yes. I made a knex replica of it. The first pic is a comparison.

Then you need to have your title say "K'NEX Nerf Reflex" not "Knex Nerf Jolt." If yours is a copy of the reflex, don't call it a jolt! XD Also, it is "K'NEX" not "Knex." I have to remind people of that all the time. And, you don't need to have "Knex" in your title, it is not needed.

Ooohh...! Now I understand!!! I didn't even notice that I typed "jolt" instead... My bad... I'll edit it soon... :/

Alright, good. No problem. =D

Changed it!!!

No problem! I can't wait to see what other Nerf guns you make knex models of.

I'm currently working on a REAL Nerf Jolt.

JonnyBGood (author)nerfrocketeer2013-05-13

Cool! Looks like your almost done with it. I'm guessing the trigger will be the harder part.

nerfrocketeer (author)JonnyBGood2013-05-13

Yeah, but i figured out something. This gun is VERY powerful though. ill post it soon.

JonnyBGood (author)nerfrocketeer2013-05-13
