Surgeon 1581 XL w nitride and XLR Evolution HD FOLDING Chassis


 Product Description

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.\


The Evolution HD rifle chassis is a premium platform designed for aftermarket large diameter receivers. Modeled after our original Evolution, it is essentially a beefed-up version capable of accommodating larger actions commonly used with the 338 LM and Chey-Tac sized cartridges. This chassis is generally used with actions of 1.45” diameter or larger. Machined from solid 6061 T-6 billet aluminum the Evolution HD is highly durable. The chassis features a 2" centered handguard 16" in length. XLR offers Evolution handguard specific Picatinny Rails, Bench Rest Plate, and Quick Detach Sling Adapters (along with other great accessories) making this chassis system fully adjustable and ensuring the perfect union between you and your rifle.
