Editing PMI Trracer (section)

=== Original Trracer ===

The original Trracer incorporated a Nelson-based inline valve mechanism.

Its bolt, striker, spring and valve were arranged along the same axis.

The pump handle operated a cocking rod, allowing the user to load a paintball and recock the firing mechanism between shots.

The marker incorporated an auto-trigger mechanism, which permitted firing during repeated pump cycles while the trigger was held.[4][6]

The Trracer was marketed with a removable barrel and could operate using carbon dioxide or compressed air.

Velocity adjustment on standard versions was performed by changing springs rather than using a conventional external adjustment screw.[3]
