  1. Kolpin Rhino Grip Pro stock restLockable butt-stock rest on your shooting side. It is also the stopper at that end of the rails.
  2. Swivel ball head360° rotation and extreme tilt, with a quick-release receiver taking three rifle mount standards.
  3. Sliding carriage plateRides the two double-width roller bearings for 800 mm of left-to-right target tracking.
  4. End stop capsCapped on one end only — the Kolpin stock rest does the job at the other.
  5. Stainless steel plated rails1000 mm and 800 mm. The 1000 mm rail always sits closest to the shooter.
  6. Alloy plate, tapered endThe taper sets the hand: right for a right-hander, flipped for a left-hander.
  7. 12V switch leadRuns up to the two self-centering push buttons on the handlebars. Underneath it all sits the 12-volt electric elevator.

02 The parts

Every P‑TAS part, on its own
