Rifle Action - F-Class Panda (Picatinny) 20 MOA, Right Bolt-Right Port
Rifle Action - F-Class Panda (Picatinny) 20 MOA
The F-Class Panda actions are a Panda variation designed for long range shooting. The dovetail or Picatinny (NON-MIL-SPEC Picatinny - Designed for use with 2-piece rings ONLY!) rail is tilted 0°20’ to compensate for bullet drop at greater distances. The F-Class Panda also includes an integral recoil lug to make it more suitable for use of larger calibers.

F-Class Panda Dimensions
Barrel Tenon Dimensions
When chambering for a Panda, Kodiak or Grizzly barrel cut the tenon 1.0625” in diameter by 1.115” for a cone bolt action or 0.980” for a flat bolt action. For an Atlas barrel cut the tenon 1.0625” in diameter by 0.692” for a cone bolt action or 0.557” for a flat bolt action. It is recommended that the first 0.110“, from the rear of the barrel be turned to 0.966” diameter. Leave the rear end of the barrel square for now.
Thread the tenon 1.0625 inches in diameter by 18 threads per inch. If you are using the three-wire method to measure the threads, the measurement should be 1.0715” plus 0.0000“, minus 0.0020” using 0.032” wires.
For zero headspace on a cone bolt run the chambering reamer in until the head-space gauge is flush with the rear of the barrel. For zero headspace on a flat bolt run the chambering reamer in until the measurement from the base of the head-space gauge to the shoulder of the barrel is 1.115” for Panda, Kodiak and Grizzly actions or 0.692“ for Atlas actions.
For a cone bolt set the compound feed of the lathe to 30 degrees. Touch the tool to be used for cutting the cone at the chamber edge and lock the zeroed saddle stop against the saddle. Now back off the stop 0.135”. Using the compound feed only, cut the cone. This should give approximately 0.007” – 0.010” of space between the bolt and the barrel. On a 338 Lapua Mag. barrel the cone will cut away some of the length if a smaller diameter section is turned at the rear. This will leave the tenon closer to 1.089” in length with a 0.966” diameter rear section.
For actions with a removeable recoil lug add the thickness of the recoil lug to the tenon and headspace length. For example: an Atlas flat bolt action with a 0.250” recoil lug would have a 0.557“ + 0.250” = 0.807” tenon length and a 0.692“ + 0.250” = 0.942” headspace length.
