Last year I picked this Minicocker up locally with the intension of keeping it for my collection. The serial number is 5759. It came with a Tippmann 98 and a nice green olive unique pack.
Unfortunately the unsightly dings on the right side changed my mind.
After getting multiple requests to sell the body I gave in, but decided to keep most of the stock parts and document the breakdown so I could eventually find another body to put the pieces back together on.
The parts I could identify as unique to this Mini STO were the valve, hammer, switch, bolt, p block, ram, ivg, and barrel.
The valve features only one side cut out with a solid base to lock the allen screw against.
The hammer has the front edge slightly beveled. The hammer looks like hardened steel and the front edge, where it strikes the valve is indented to increase the amount of time very slightly that the hammer is moving but keep the same mass. I mentioned the threads are 1/8th x 24 for modern lugs.
The switch uses the smaller 3×56 barbs with tight spacing, first used by Russell Breeden of RKB Engineering and later used by ANS, Shocktech, Dye and Belsales. The stock switch on the Minicocker was likely machined by WGP for Belsales and sold by Belsales.
The bolt is a more compact P Block bolt, to fit the 99 Mini STO’s P Block body.
The P Block itself is similar to what came on most STOs of this period, but is not stamped with the last two digits of the serial, which early STOs featured.
Here is the inside view of the P block.
And the outside view.
The Ram features the flat front edge, which I believe is identical to the Shocktech Rams. The Shocktech rams were possibly manufactured by WGP and sold as Shocktech parts?
The IVG is the standard 3/16 adjuster screw style but is either plated brass or stainless. The majority I’ve seen from WGP are brass so I thought it was unusual to see a plated or stainless adjuster.
The barrel is a WGP branded J & J barrel.
This body also featured a plated brass detent.
