Introduction: Shift: an Adaptive Magazine Rifle

Picture of Shift: an Adaptive Magazine Rifle

Well here it is! Shift is one of my best concept knex guns. It's built off of the idea that you can shoot whatever you have available, whether it be yellow rods or smaller blue rods. This gun would be awesome for a war but, unfortunately it is a little slow to use, so for a knex war it needs a better rate of fire configuration. Overall it's a great rifle with at least 40ft of range. It's also my first gun made to hold as many bands as you can fit.

Now as you can see I included some internal pics(like the Red Book does...), but I know for some that's not enough. Like what you see but need more pictures? Send me a comment. The large size of this gun was a little out of my element, and a little more of a chore to document completely. So if you want more pics please tell me soon while I still have it.
Thanks and please vote for me in the contest,
JonnyBGood------------ Note: I made this ible' on the instructibles app so the internal pics are posted reverse of my intended order. So all pictures after my 22nd picture are posted in reverse order. Sorry about that.

what is the purpose of the two grey 2-slot connectors in pic 13

JonnyBGood (author)SumRndmGuy2013-08-20

Aha! Finally a question about one of my guns!! =P

Anyway that keeps the ramrod from coming up with the firing mechanism. If you look at the internal pics you will see that the block is very close to the back of the gun which didn't give me a lot of room for a guide (granted that is what the stock is for) and also I didn't want to add friction on the pin from the mid section of the gun.
Overall it is really not necessary unless you plan to make this gun exactly as I did, although I wouldn't recommend it. Competitor Rival 107 uses the same mech as this gun but I improved it so it wouldn't need that little part so feel free to look at that gun as well for a better idea.

alright just looked weird

JonnyBGood (author)SumRndmGuy2013-08-20

It is and it can so easily be avoided if I built it better.

JonnyBGood (author)2013-08-07

Yep, I don't think my method was the best but at least I tried. Like I told Red it'll work much better it the barrel side don't move with the adjustable magazine well. to much friction.

JonnyBGood (author)2013-08-07

Oh... hmmm... well I didn't look at his before starting so I guess this isn't quite the new concept I thought it was...

If I did not know any better, I would say that your rockem and sockem robots are you winner! ;)

JonnyBGood (author)hunter9992013-07-24

Yep, I'm kinda banking on them to bring me home a t-shirt. That's what I really want out of all the stuff. You are right though my big ticket item are my two robots.

hunter999 (author)JonnyBGood2013-07-24

Same here, all I want is the t-shirt! I don't really care about the knex!

JonnyBGood (author)hunter9992013-07-26

Although more knex is always a good thing. =D

hunter999 (author)JonnyBGood2013-07-26

Of course! Also did you see my knex table (my latest ible) -

JonnyBGood (author)hunter9992013-08-07

Yeah, looks pretty cool!

Very nice! The concept to use different ammo types is very clever.

Oh voted :)

I took the one i made apart to make a mortar that i will be posting when i work out the kinks

JonnyBGood (author)2013-07-26

Well I didn't know there were any other guns like this one. Anyway thanks!

halofreak101 (author)2013-07-25

I was working on the same thing :(

JonnyBGood (author)halofreak1012013-07-26

Well, continue working on it. I'm pretty sure that you built it better than I did and I am personally more of a fan to a more portable size gun so I've already started planning Shift 2nd gear.
Also my new one won't have the sides of the retractable mag well so close to the chamber because that's adding a lot of friction and problems.

Wow! This is quite interesting! I like it. : )

Thanks! Glad you like it.

Nice job bro, this is pretty great. I knew it was coming, but still, good job. =D

Yep, you definitely knew this was coming. Thanks anyway!

XD, yes, yes I did. You are very much welcome. =D

Nice idea, I like it =)

hunter999 (author)2013-07-24

Awesome work, good job! =D

If you didn't like it to be that big, you didn't have to make it that big. Much of the front end is extra parts, as well as most of the stock.

JonnyBGood (author)TheRacker2013-07-24

Well, I always wanted to make a large rifle, but I found out afterward, it's just not my style. Shift II will be smaller a more compact, not to mention more convenient. Thanks for the suggestion though.

nerfrocketeer (author)2013-07-24

Cool! Gujob bro! :)

JonnyBGood (author)nerfrocketeer2013-07-24

Thanks bro =D

nerfrocketeer (author)JonnyBGood2013-07-24

Sure bro! XD
