Specialized Tools To Accomplish Your Mission

591 Short Action WSM

All 591 actions are designed with an integral .250″ recoil lug and 20 MOA 1913 MIL-STD picatinny rail that runs the full length of the action. A side-mounted, shrouded, bolt-stop is integrated to help prevent accidental releasing of the bolt.

In the middle of the left bolt raceway is an anti-jam rail. This rail is designed to prevent a round from lodging in the raceway when single-loading the rifle through the ejection/loading port. The raceway on the right-hand side has an anti-bind rail just below the ejection/loading port. The purpose of this rail is to insure smooth bolt operation as the locking lug passes through the loading port.

The WSM action has a longer loading port cut in the bottom of the action and bolt stop to match, and the internal feed lips of the action are widened. The purpose of this is to allow the use of extended internal box magazines like Wyatt’s. (So if you are going to be feeding the rifle from Surgeon DBM or any other system that uses the AICS mags there in no need to order this action you can use the 591/R and upgrade to a .550 bolt face bolt).

*All Surgeon Rifles™ actions are shipped uncoated and include a tactical Surgeon Rifles™ bolt knob (0-ring bolt knob shown available at additional cost).

**All serialized products must be properly shipped and transferred through a dealer who posses a valid Federal Firearms License (FFL). On ordering, a representative will contact you to verify your preferred FFL for shipment.
