Paintball

[Neo_samurai]

has anyone tried this before? I just think it would look too good to have a nice clean barrel up top and the feed imbedded into the stock... aka hidden

please let me know

What gun are you hoping to do this with? You could do it with a mag I suppose. Need to stick the detent on top like a warp breech.

There was a very short-lived gun that used a banana-type clip that loaded paintballs from below. It was basically a Nelson based pump otherwise. I think it was called the "PS__ Marauder" the blank is a number which escapes my memory.

I am sure that you can find a pic and info on VintageRex, but alas, I am too lazy to go and get it for you.

Good luck and let us know what you come up with.

I've thought about doing this with a spyder i'm working on. I'm thinkin of making it look like an over/under shotgun type, except the paintballs would load through a springfeed clip mounted on the bottom of the barrel. I was planning on cutting off the powerfeed then capping that top hole off with copper sheeting. Then I plan on mounting the springfeed underneath with a hole cut in the bottom of the spyder, just in front of the valve setup, and then put the powerfeed tube on there with it loading upwards into the gun to where it still seats the paintball behind the detent. I don't know if it will work, but i'm gonna give it a try.

I'm looking to make a sawed off double barrel lever action pistol grip shotgun "marker"... based off of two traccers

It's far from even getting started... but i really want to figure out some way of making it an underfeed to preserve the bad *** double barrel look... and hide the feed tube...

call me crazy... cause i think i am

Hey i'm all for the bad *** look. I've got a spyder that's going in a wooden stock to do a milsim WW2 rifle. Which springfeed mags are you gonna be using? As soon as I get a leak fixed in mine and throw the springfeed on, it will be done as far as putting it all together. I still need to clean up the stock and fix cosmetic stuff. The feed system is the thing that's getting me. That, and the dang trigger assembly. I'm building my own trigger setup, without any custom tools, so it should be interesting. Let me know how yours goes when it gets started.

I was wondering this myself, doing it to a KP style rifle. Has anyone with a spring feed ever tried to see how well it feeds when the feed is directly underneath the gun?

I'm actually planning on doing this myself instead of having a feed along the side.

I don't think that's going to work sir..the entire bottom tube of the Spyder (or STBB) is pressurized at some point or another. The section forward of the valve is always pressurized and aft is pressurized during the firing cycle. The only way I can see you'd be able to underfeed a Spyder is to load directly into the barrel forward of the barrel threading/VA.

Also, putting copper sheeting over a powerfeed hole might not be structurally sound (or safe). Spyders fire at around 800psi, and since you're looking at about a .75 dia hole you're putting around 350 lb of pressure pushing that plate outwards, so you'll need some heavy duty welding/brazing/screws holding that plate to the body. You might be able to "swiss cheese" it to reduce the area and therefore the force on the attachment, and still prevent balls from sliding out, but you still have another problem. If you're pushing balls into the breech from below, you have to make sure there's no lip between the cover plate and the top of the breech, or balls will be pushed into it and chop.

Underfeeds work best with single tube markers like Nelsons or Automags because there's nothing under the breech getting in the way. You just basically cut the feed hole on the other side and attach a screw for your springfeed.

As far as I know, the (el cheapo) Splatmatic .50 pump is the only underfed production paintball marker. The pump action only charges the pneumatics (it's spring powered), it uses a dual nubbin type detent to hold balls in the breech, and the magazine spring indexes balls as soon as one is fired.

The spyder i'm fixing up right now won't be the one I was gonna try the under barrel thing on, because I can't cut any more out of my stock. It was a theory. Thanks for the heads up

They feed upside down, I've done it with a squall.
