Pumps's AT kit for Cocker slider frames

thumper · 06-13-2008, 09:54 PM

I got one of pumps cam/lever combo AT KITs for auto-triggering a SniperII with a slider type frame..

first, let me say I cheated. Im using old wgp sniper II style trigger and sear for trigger guts. (most of his plans lean towards an epoxy filled slider plate)

My first attempt was on an old wgp carbon fiber slider frame (the thin one) that I had "hinged" -- the pump kit was a stock wgp, with tapped pump rod from pbmodshop.

the cam was a bit tight in the carbon fiber frame, and I didn't feel like drilling the safety hole so I broke out another gun.

The second attempt was a 2k1 sniper II w/ stock wgp pump kit w/ pbmodshop tapped pump rod, bob long 45 frame that I has "hinged" as described above.

I also had a 4/40 shoulder screw I picked up from pbmodshop for $2 (I think they get these from chipley)

I had to file a bit of the cam to get it past the trigger, but in 15 minutes this one was AT'ed.

here is the before pic:

..test driving this weekend at a scenario near myrtle beach.. but so far I'm pleased. pretty simple if you have the right trigger guts and tapped pump rod --- more to follow

I ran Pump's AT rig today at a scenario game down near Myrtle Beach. The woods were thick and far from "pump friendly" and we were sided against a fair number of ego toting uber shooters. Ide call it a good test.

As far as AT kits go,

Ive got my home brew version on an 99 evo X, (bottom right)

a CCM 86 degree slider w/ delux pump kit w/ CCM CAM on a 98 evolution, (middle right)

Ive played around some w/ my CCM S5 with the same AT rig above (86 deg) (top left)

ditto on a free flow body (not pic'ed)

comparing these:
CCMs frames , AT kits w/ the full delux pump kit are extreamly smooth, no slop, and feel like they are factory made for whatever body they are on. Free flows, evo's, S5's - what ever. all kicken.

My home brew job 99 evo X feels much more crunchy - fast and light - but definitely not as finished feeling as a full CCM rig.

Pump's AT rig on the 2k0 sniper II pic'ed (middle left) feels very very similar to the CCM and nothing like my 99 evoX - it is very smooth and finnished feeling and I was frequently suprised at the volume of paint I put out. I dont think ive ever cycled a pump like I can (and did

) w/ my kid's 2k0. The smoothness and finnished feeling helped me keep the balls on target. Im pretty sure I can pump that lady on par with what I can produce w/ my evo cocker (top right). Its obviously harder to keep the balls on target while pumping, but I think with practice that will come too.

Im ordering 3 more - plan on replacing my home brew rig on my 99 evo X and the other two just to mess around with.

one tip for the wise: the AT lever will come in contact w/ the body unless something helps it stand off from the body. It doesnt really rub, but I can see where it could scratch the anno. Im experimenting w/ a thick rubber washer placed between the lever and the pump arm on 4-40 shoulder screw.

Two major thumbs up Pump.

iya......i forgot to put stotch tape on the side of the lever........works guud....i normally do that on all the ones that go out......stupid stupid stupid

thumper · 06-15-2008, 08:19 PM

i forgot to mention, this was the first time (in 17 years) I readly needed my revy loader while playing pump ... My indian springs maxiloader XL could not keep up. It needed shaking 4-5 per hopper full.

pump: check out the rubber oring in this pic:

works great so far w/ your lever - a bit cleaner than scotch tape. I dont know where to get them - found a few in my kid's erector set.

oh i normally supply small plastic washers with the shoulder screw

bah another brain fart

I just got in a handfull of pump's levers and cams and whet to my original wgp pot metal hinge. the cam is a bit fat for these frames - so I drilled the frame's safety hole out w/ a 13/64 bit, and cleaned up the guts a bit - and bingo. 20-30 minutes tops.

a small metal washer serves a spacer between the pump arm and lever.

I also tried it quickly out on a dye single hinge -- this really would be a piece of cake. just drops right in.

So it drops right in, as in no modification of any kind? Mmmmmmmm....WANT!

Man, I have one of those frames and thought about selling it, well not anymore.
