pneumatic assist trilogy cocker

[dcent]

not a mag but figured I might get some info off you guys.


just finished and it works perfectly.

got plans for the back block ( cocking block or whatever its called )
not going to get rid of it but might cut it up and make it unique ( move the half attached to the bolt forward to where the body is cut )

also I have a dotted line where the valve is and arrows where I believe the air passages are. If anyone knows different and can tell me where I can put holes in the bottom tube ( Im thinking only behind the valve but I may be wrong )

This project has been done before,.. but let me say CONGRATS! I wish I had persued this more when I was looking at it myself!

Id be interested in "shop talk" with you on the directions you went.

Looks like you ties the 4-way to the pump handle,.. that was what I was planning to do,.. but with a removable 4-way flipped backwards.

Whats your pump handle stroke at now with the mods? I figured 1/4" -1/8" depending on the 4-way used.

The original was called the "SHO Sniper II" (SHO = Super High Output) I first saw one at a pump tourney back in 2000 when I was stationed in Jacksonville NC. It was an awesome piece of work!

Do you have any video of it?

Again,... kudos on your work!

pump stroke is at 3/8ths right now.
I could go as low as 1/8th but I was worried about short stroking so I allowed more room than necissary.
I think Im going to use bondo or JBweld to shorten the slot in the pump handle that limits the stroke. then sand it down untill my pump stroke is closer to 3/16th.

no video.

I did shorten the hoseing and re route some so it looks a bit better ( no slack between grip and LPR anymore and 1 hose going under the cocker body, 1 under the barrel )

once I finish chopping up the back block I will post new pics.
