=== IMP conversion system ===

One of the company's principal products was the '''IMP''', a mechanical semi-automatic conversion system for existing pump-action paintball markers.

The IMP used a direct-blowback operating mechanism that automatically recocked the marker after firing, eliminating the need to operate the pump handle manually.

The original manufacturer advertisement described the system as operating from an open bolt using liquid CO₂. It also promoted a semi-external velocity regulator and the ability to return the marker to pump-action operation without extensive modification.[4]

Cooper-T marketed IMP kits for Sheridan/PMI markers and the WGP Sniper platform.

The original advertised prices were:

* '''Sheridan/PMI IMP Kit:''' US$134.95.
* '''WGP Sniper IMP Kit:''' US$174.95.

The manufacturer also advertised an optional back-bottle adaptor for the Sniper conversion.[4]

VintageRex dates the Sniper version to 1990, although its records do not establish a confirmed introduction date for the Sheridan conversion.[5]
