Autocockers, 12 Grams, Regulators, etc

Ugh, I’d kill for a feed tube set up like that. I’m trying to build a stock class cocker pump and can not find a metal feed tube set up.

[Chuck E Ducky]

Cocker pump machine the top and mount a CCI one piece feed. That two separate hard to find and very pricy CCM feeds. You would need a Spyder style feedneck mount to use this setup anyway. You can machine off the feedneck and drill it to CCI dimensions a lot cheaper then you could buy this style feed.

[Tomtheowl]

The cocker pump I have I don’t wanna cut the top off of. But I could always buy another body…

[Chuck E Ducky]

Well they do make a feed that goes in the feedneck that runs horizontally. I personally prefer the older aluminum feeds but There are some Delrin and Benji at Paintball DNA makes a bunch of different printed options. You don’t have to lol the feed off. I’m working on a detacated SC sniper I need to get a new spring kit tho so I can do some more testing. I just snagged a Stock for it today in the BST.

[Chuck E Ducky]

Got to play with the springs and reg input pressure some more. Messing around with some devolumizeing options see if I can get some better numbers that way. If I get it tuned nice I will probably send it to Mozak for a lil customization and the out for Ano or Cerokote. Just need some trigger time with it see what I can do with it.

What valves do you guys use?

[Chuck E Ducky]

I like that, Carter would be proud. Thats super clean you should make some more and add a Spyder style mounted plate so they can be bolted on a CCM. That would look killer on a T2 or T2F!

[Grendel]

I have never made a Sniper II setup for CO2 cartridges and max efficiency ( I have done stock class but not worried a lot about CO2 efficiency). Any of you experienced in this have you use a Mini-body to help decrease volume in front of the valve? I was thinking that that would serve as a good place to start.

[Chuck E Ducky]

I’m using a standard WGP valve I believe, it’s also got a printed piece in the lower tube to fill volume. I purchased the prototype from another member to do some testing. The idea is lower the volume on a 2k+ to that of a Pre 2k. Possibly making a drop in co2 performance kit for any modern SC Sniper setup.

I’m going to drop the part in my CCM that’s well sorted and balanced already see how it affects efficiency numbers. It will make a good test bed since I already know what it produces at full 2K+ volume.

[Jordan]

Are you hoping to do a side by side comparison - devolumized vs normal volume - with 2k body? Or just come up with an unregged setup solution for 2k bodies?

[Chuck E Ducky]

I’m regulating both setups. My CCM hits 30 regulated @280FPS +65*F I’m hoping to have a base line. The WGP body I’m not exactly sure what springs or valve is in it. My CCM is all stock I don’t even adjust it at the IVG for 12g play most of the time as long as it’s above 65* it shoots 280. If I get a boost in FPS or Shot count I know I’m going in the right direction and can start playing with different spring ratios.

My 2000 PTP (CCM lower, AKA bolt, reg)
36 total 34 lasers @ 280

My 98 WGP (CCM lower, AKA bolt, reg)
34 total 32 lasers @ 280


My experiences with devolumizzing differs from the rest of us. Makes me not want to try any pre 98 bodies after hearing results of people I actually know who have … 25 range.

I have a 92 Mini that should have the smallest volume of all based on the smallest passages of any of the cockers. According to everyone’s else’s data etc that should be the most sought after body for all of this if devolumizzing is king. My experience differs.

However, there are multiple reports of 40+ shots on pre 98s on the internet . I haven’t discovered the magic sauce for that. My experience in the back yard has shown for my markers a 2K+ has more shots from the food grade 12’s I used.

[Chuck E Ducky]

Hellions SC Sniper shoots deep into the 40’s it’s a Pre 2k. My biggest issue with a pre 2k is there are very few center feeds and they are often expensive when you do find them. I need a center feed due to the way I aim.

[Pump&Run]

I would love to know his specs so we can replicate it. I believe between the group of us ie Caveman etc we have the slabs covered for testing.

See everyone’s differs!

Yes, the pre 2k vertical feeds get spendy and not a lot floating around.

[Chuck E Ducky]

I’m waiting on some springs from Autococker parts to do some more testing see how the part I’m using effects efficiency. I would love to create a SC drop in kit for a 2k+ body.

[Hellion360]

@Pump&Run I'm cheating with a check valve. It only gets into the 40's if you don't dump the chamber. But as long as you don't completely clear the line your efficiency on your 2nd 12gram is through the roof. The initial pressurization eats up a lot of co2. My other with no check valve gets into the mid 30's.

Specs though are otherwise similar
pre 97 valve chamber.
PPS or Sheridan valve (small inlet on these)
Stock bolts with tight openings and 3 orings

And that's it. Nothing special other than regulation. Lighter hammer springs than the valve spring.

Also worth noting that the early snipers easily get 35 shots unregged straight into the ASA with stock sheridan style internals.
