Takedown is as simple as locking the bolt back and verifying that the rifle is unloaded, pushing a recessed lever, twisting the subassemblies and pulling them apart.

Bolt is machined from heat treated, chrome-moly steel to ensure strength, structural integrity and durability.

Cold hammer-forged, chrome-moly steel barrel with ultra-precise rifling provides exceptional accuracy and longevity. The heavy contour barrel provides consistent accuracy, while barrel fluting sheds unnecessary weight and allows for quick handling.
