Designed for the competitive shooter or hunter who is looking for the lightest possible rifle, the ØRN | Stalker far exceeds expectations, weighing in at only 5lbs.  Without the bulky components of many rifles, the Stalker exhibits a sleek profile yet maintains the same toughness and durability.

The Receiver

The foundation of the rifle is our ØRN lightweight lower receiver.  This receiver is the culmination of 3 years of development.  By focusing on redesigning the AR lower from the ground up, the ØRN contains only the material absolutely necessary to maintain significant strength.  While many “light weight” receivers shed weight by skeletonization, the ØRN receiver maintains the closed system that makes the AR such a dependable rifle in a variety of environments.

Furthermore, the ØRN lower receiver features a flared magazine well to aid in reloads during high stress scenarios in hunting, competing or during Mil/Leo scenarios.  Relief for the trigger finger on the forward sides of the trigger guard enhances trigger finger placement when not shooting. Our trigger guard is enlarged for use with gloves. This is accomplished without significantly lowering the trigger guard as many receivers have done.

The ØRN lower receiver is paired with a Battle Arms Development upper receiver that is custom finished to match the lower receiver specifications.  Lightweight and contoured, the upper receiver flows perfectly with the ØRN lower.

The Barrel

The ØRN | Stalker features a lightweight Criterion pencil contour barrel chambered in .223 Wylde. Criterion barrels are absolutely excellent and they are manufactured in Wisconsin.

Smooth Cycling

All of Ox Firearms rifles feature JP Enterprises Silent Captured Spring Systems.  The JP Spring System excels at significantly absorbing recoil and reducing muzzle rise.  Despite the light weight design of the Stalker, the recoil does not increase, thanks to this incredible spring design.

Enhanced Controls

The ØRN | Stalker features a Timney competition trigger. Timney is known the world around for their excellent quality triggers. They are simply the best trigger available.

Additional control features include an ambidextrous safety selector, an extended magazine release, and an enhanced bolt catch.

In the mission to decrease bulk, titanium components have been selected to accomplish this task: Buffer Retaining Plug, Endplate (QD Mount), Castle Nut, Takedown Pins, Grip Screw and Ejection Port Door Rod.

All of Øx Firearms’ rifles are shipped with two Lancer magazines and a Pelican case with custom cut foam.
