1581 XL Action RepeaterActions
Measuring in at 1.450″ wide and 9.5″ long, the 1581XL action is the largest of the Surgeon line of actions. It comes with a full-length 30 MOA integral 1913 MIL-STD picatinny rail, a huge .450″ integral recoil lug, and a large 1-1/8″ x 16 tenon thread, which requires the use of a 1.350″ diameter barrel.
The 1581 actions utilize a removable trigger hanger that was built for Remington 700 style triggers. 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. Similar to the Surgeon short and long actions, the 1581Xl has a side-mounted, shrouded bolt stop to help prevent accidental releasing of the bolt.
*All Surgeon Rifles™ actions are shipped uncoated and include a tactical Surgeon Rifles™ bolt knob (standard bolt knob shown available at additional cost).
