Bolt Action Rotary Magazine Gun (updated with internals)

Alright, it's been a while, forgive me. I work in spurts of an hour or two every few nights. It's not quite finished, but it's at a point I'm comfortable showing. I'm also working with BM, so hopefully he can make some improvements on it before it's posted. 

This gun is the combination of two different goals I've had. First off, I always wanted to make a bolt action. I came up with the idea for the modern bolt action long ago but was beaten to the punch. So since then, as others have made their own bolt actions, I still struggled to make one up to my own standards. I wanted something sleek and compact with a removable magazine. 

Second, I went off on a little tangent while building, which then turned into its own project: a rotary magazine. While it's been done before, I don't know if it was ever successfully used in a gun. It's more about the novelty than the practicality, but what it does do is give you more storage in a compact design and act as a decent foregrip. I wanted to make it a decently usable. At first I thought of making just some cruddy gun to show off the concept as a usable magazine, but then I decided I may as well go the full nine yards and make it perform well. 

So this is what I ended up with. I don't have a real name for it yet, but I've considered calling it the Barackuda, a portmanteau of Barack (Obama) and barracuda because...well why not. I wanted to keep it as compact as possible, so I used a barrel similar to my Oodassault 3 series and a stock connection similar to my PDR. The stock is a bit long compared to the body of the gun, so it may look awkward, but I wanted to give at least enough room to aim the gun without sticking the pin into your eye. The blue connectors in the stock stop the bolt right after the trigger engages. The bolt is somewhat typical. I like how it sits flush with the back of the gun rather than looking like an extension on the back of it. The handle isn't amazing, just a variation of my tried and true handle I've come to like. The trigger also isn't amazing, and in hindsight, I want to block a bit further back still, but it works for the limited space I've got.

The magazine on the other hand is magical. Go look at my last topic for details on its operation. This version is for yellow rods. I've added a rotary lock and band. When the middle rod is pushed toward the trigger (like in the pic), it's locked. It can securely contain 10 usable yellow rods while locked, though it can load up to 12, the top 2 can fall out. You insert it into the gun by pressing the top two red rods at an angle into gaps in the grey connectors at the front, then rotate the magazine, slightly pushing in, until you get the white rod in the gaps of the yellow connector. Finally, you push in the middle red rod by the trigger all the way forward to unlock the magazine. 

Edit (9/10/2015): Made my adjustments and now I'm mostly satisfied with the weapon. Here's the video.

It would be great to get some instructions I want to see if I could build this Mag into a Bullpup.

Yeah, sorry, I kinda neglected getting instructions. I'll be busy after work today and over the weekend, but I'll try to get some pictures soon.

That'd be interesting. I was playing with the idea of making a bullpup version of this gun myself. But I'd probably make it too flimsy by that point. I'd like to see where you take the concept. The magazine isn't all too complicated, I could at least rip open the side quick and show you the insides.

Great! I want to build this gun first so I can see how everything works before trying to make a bullpup. Some pix with the side ripped off would be great I can build from those.

Decided I'd get pictures first thing getting home. I've updated with internals.

Thanks I'm going to get building!

TheDunkis (author)  sonic broom2 years ago

Good luck! Let me know how it goes.

TheDunkis (author)  sonic broom2 years ago

Fair enough. The stock isn't very important, just what I sorta threw on there, so I'm not going to bother with pictures for it. I'll definitely get some closeups of the open side layers, magazine, and bolt though. And I hope you can figure out a better trigger and feed ramp. With more room from a bullpup, I assume it should be easier.

For kicksies I added another pair of bands finally. Such an annoying process and definitely not something I'd want to do on the fly at a war. Sadly, my fears about yellow rods still held. They do get more range, but it's a crap shoot whether you'll actually hit what you're aiming at.

I'm finally getting my fill of the gun, so if I can't think of any other improvements to make, I'll get internals as I deconstruct it to start another project.

Oh yeah, forgot to mention I also figured out how to adapt a vertical magazine for my weapon, though it would look ugly and in my opinion, it wouldn't even be as practical as a rotary magazine. Instead, I'd rather make a speed loading tool for the rotary mag so it's not as much a pain to reload.

So how far does it shoot?

That's what I hate about yellow rods. Best suited for a pistol, since yellow rods are so inaccurate they don't need much range. Better to have a good ROF with rods, I suppose.
