A cylindrical three lug action, basically a Remington exterior configuration (almost a drop-in to a stock inletted for a Remington S/A).
The receiver is of 4340 chrome/moly/nickel steel through hardened to 38Rc and finish machined after surface hardening to ensure concentricity. Recoiling options are either a Remington style recoil lug or a 1/4" x 28mm cap screw from the action into a steel lined hole in a bedding block. The bolt is equipped with a Sako type extractor and boltface plunger type ejector as standard. This action is supplied as standard with no trigger, but with a hanger to enable fitting the trigger of choice (such as any "Remington style" clone). Single-shot configuration only.
