Ten Round Feedtube- Concept Drawing

[WingMan13]

Aww man, I have been wanting a pistol mag for some time as well. I wouldnt mind a SS body as long as its spring fed, feed tube a bit off set to the side as to sight down the barrel and just enough gap between the tubes to slide on a rail for some optics.

I love it. I was looking for this exact same thing a couple of years ago and couldn't find anyone who would attempt it. I personally would prefer rockNcock but I would take what was offered. Will the cost be similar to your other feedtube mods? I know there will be more details in the dealer thread I'm just curious.

Sorry guys IF I do this, it will be for SS bodies only. No threads- non removable welded to the body.

All SS bodies would be eligible, including Centerfeeds.

I will lower the tube to the surface of the body, NO problem. (I'm busy the next 3-4 days but I'll redo the drawing) I'm also going to remove the rear spacer, it really dosent need to be there and it just drives the cost up.

I will gladly look a a spring feed design if someone can turn me on to some ideas. Was the sidearm spring feed or rock-n-cock? At this point I don't see why I couldn't offer both.

For you guys that want to use a removable system that can be purchased on the market (held on by a set screw), I can redo your powerfeeds with a short tube coming straight off the body. (Like a cut down Automag feedtube, non-powerfeed) This I can offer today.

What's involved in the sprinloaded cap? If it's just a matter of "space" that's no problem. That is easily adjustable. Really don't know anything about it.

The AGD sidearms have a spring loaded cap. That's about all I know about them.

I'm looking for one to be springfed. Trying to make a pistol, and the idea of a 10 shot semiauto pistol that I have to rock to feed really bugs me.

Simply mill an "L" shaped channel along the tube that a nubbin type of device slides through. Attached to said nubbin is a plate that pushes your spring back so you can load the thing. This will also require a paintball sized hole in the tube just above the actual breach opening. Cap off both ends after placing your spring assembly inside.

Essentually this will look just like any springfed pistols magazine. Only attached to the mag.

Also, they would have to be a bit longer than originally planned to accomodate the 10 PBs planned to account for the space taken up by the spring and such. But shouldn't be a problem.

Also, could you mount it facing forward, like a pistols mag?

Can anyone provide pictures or drawings of these?

I'll do some searching as time permits, I'm just a little busy right now.

Thanks

The Sydarm uses an internal (welded) fillet-shaped insert to direct the balls from the feed tube into the breech.

The cap, spring and follower move front-to-rear to feed the paint against the baffle and into the breech.

The Sydarm is loaded by drawing the magazine follower forward and locking it into position using a small knob. This uncovers the feed port located in the extreme forward top section of the magazine tube. 8 rounds are loaded and the follower is unlocked and spring force drives it rearward. The follower covers the feed port as it travels.

This type of feed can be put onto other springfed magazines somewhat easily.
It's not the best example but you can see AgentSmith's here.

I can take pictures of a Sydarm later if they're still needed.



The reason why you need to move the feed tube out and away from the body is because the Phantom-style feed gate will hit the valve, yes?

You can simply extend the feed tube so that the wider gate section is past the rear of the marker. Even us stock classers prefer a 12-13 round feed just to give you some buffer room for reloading.


I think it is a very good mod and I would be willing to have it done.
You don't, by chance, also do rail + body milling for a pump kit, do you Luke?

personally, i think springfed is a bit over excessive. i play with my pistol mag all the time, and the paintballs always find their way down the tube and into the breach. having just a simple SS tube for balls is just find, and will keep the cost low.

Using one of those phantom feedcaps is perfect for the tube, but will have to be taped down since it isnt a 100% fit. having a 6.8" tube is probably a good enough length to attach a feedcap at the end without hitting the valve, but it is the distance between the feedtube and the body that could be a problem...unless the tube was extended more behind the valve, just like what pumpplayer said.

But there are a lot of single tube (Non-spring loaded) loaders available aftermarket. Granted there aren't any available at all for SS bodies, there's still an overall lack of spring-loaded feed tubes available aftermarket. That's why I think this will be a nice addition to Pump-Maggers.

Pictures would be great. I didn't see the picture in your link.

No reason really, it's just a concept drawing to get the ball rolling on the design.

You can simply extend the feed tube so that the wider gate section is past the rear of the marker. Even us stock classers prefer a 12-13 round feed just to give you some buffer room for reloading.

All that is adjustable, it dosen't matter to me, what ever you guys want.

You don't, by chance, also do rail + body milling for a pump kit, do you Luke?

No I'm not offering that milling, sorry. There are 2 problem areas in the pump slot tool path that can not be done a cleanly as I would like. There is another guy in the dealer forum that is doing them.

No, I heard you.

I did say several times I can do both. The rock-n-cock is a no brainer. All we need is a cap, can you show me a picture?

you mean of the feedcap?



Here it is on a powerfeed:



but on the powerfeed, it wont hold well. if i face the feedcap downward, and make one quick down and up movement, it will fall off.

(wow, pictures are suppose to be smaller... darn photobucket )

This is a great idea, luke. I've been thinking about a pistol 'mag, but the main thing that's kept me away is that I don't want to shell out for a ULE body just to put on it. Springfed isn't a necessity, either. Anyway, I'm subscribing to this thread, looks very promising. Any guesses on price, or not at this stage? Cheers!
