View Full Version : Quick Question....

How would I go about making a stock class feedneck on a normal feedneck like on a Spyder? Simply put a PVC pipe with tightener and an elbow on the feedneck?

Thanks in advance for any help!

You can use PVC and a hose clamp. Ive also seen some very nice brass setups. Just go to the hardware store and get creative.

OK, thanks guys. :) I knew this was the section to come to for this question!

Somebody sells a premanufactured version also...forget who. I need to make/get one too.

Druid said that the 3/4 inside diameter was the right size for a stock class feed for over a Spyder. You might need a different size because of feedneck styling ('Cockers, for instance) and may need a bigger OD for inside the feedneck.

yep......3/4" ID Copper tubing 90* elbow fits right over top...a smidge loose as a matter of fact. The copper tubing for the 10 rd is about 6.5" long.

so you need:
1 90* elbow 3/4"x3/4" ID
1 3/4"IDx8' length of copper tubing to get 14 tubes
14 copper end caps
1 coil acid core solder/flux
1 torch
rough sand paper

Palmer's Pursuit Shop sells a pre-made clamp-on feedneck. Every time I suggest it though, people flip out about the price. $35 for the black. Another $10 for nickel.

It is somewhat expensive Dave, but i hear it's well worth it. I don't like the way the PPS tube is setup though, i think a 90* brass elbow and then maybe 5" of brass tubing with a big enough diameter to fit a 10 round tube in would be a good idea. If you had that setup then you could just slide a 10 round tube into the brass tube then when you needed to reload just pull the 10 round out and slip another in. Don't have to buy 8' of brass tubing that way.

Yeah, I would like something that does what The Magician described. And I plan on spending $5 total, so $35 ($45 if i go for the 15rd version) is a bit much. Thanks anyways, Dave.

While I'm at it, I'm gonna be lazy and not start a new thread to ask another question.....
Would you reccommend a 12g changer or a 3.5oz CO2 tank for a stock class marker?

What kind of marker?


03-20-2006, 02:48 PM
If you go the brass slide-in route, there's a way you can cut and bend the lip of the brass so that it acts as a pressure lock around the lip of a 10rnd tube. Ive seen it done and I'll try to find a picture.

It's on a Spyder style marker (wont say for sure until this project of mine is done).

I'm asking everyone that knows what I'm doing to please keep their mouths shut until I'm done, thanks (this means Druid and Bomber....yeah, you two....). :)

Well if it's a blowback marker and not a marker than was meant to be a pump then i would say 3.5 cause you won't get alot of shots off of a 12g.


03-20-2006, 06:01 PM
Well it would be an ubber efficient former blow-back, only using about 150-250psi per shot. I dont know what the OP of most pump markers is, but I would assume it's around there...or mebbe even higher.

Just throwing this out there... and I'm not sure why its true, but it is. 12gram CO2 works very different from bulk tank CO2. For example, having a larger chamber and a more open, free-flowing valve tends to work better for bulk tanks... allowing you to lower your operating pressure and get more shots per tank. But on 12grams a larger chamber volume and free-flowing valve will either give you inconsistencies or drastically reduce your number of shots per powerlet.

Thats why older-model Cocker bodies make for better stock class sniper conversions. They have a smaller internal volume so they're much more efficient on 12grams.

Just throwing that out there.

Well it would have a small internal volume, not sure how small as of yet, but it would be about the same as a Spyder without the LPC...I don't have an older 'Cocker so I couldn't tell you how it would compare size-wise.

I think it might be the fact that a 12g is smaller so most of the gas is released into the large chamber of the marker and it lowers the pressure or something. But that's the exact reason i went for a pre 2k sniper, so i can do SC conversion if i want.


03-21-2006, 08:48 AM
Yeah, that's my bet as well....I guess to really find out what will work best I'll need to get both, try them both, and sell the one that doesnt work well. Thanks for the input, guys!

Sounds like a good plan.
