The MRX Bison is a compact, light and rugged bolt action rifle that is chambered in 5.56 NATO and is fed with AR15 magazines. This rifle would be comfortable in its scabbard on the side of a horse, packed, slung or mounted onto a Utility Vehicle for ranch, range or backcountry duty. The vertical pistol grip and adjustable stock allows for the rifle to be shot comfortably in any position and the magazine will continue to feed up to 30 rounds of ammunition (based on legal magazine capacity in your area). In addition to being compatible with AR15 magazines, the MRX Bison also feeds from the MRX MAG bolt action magazine, which is a 20 round magazine that has longer feed lips and a follower stop that (unlike AR15 mags) allows the action to be closed with a fitted, empty magazine.
- True bolt action chassis machined from aircraft grade aluminum and finished with Type III hard coat anodize and Cerakote. The chassis comes with side and under rail MLOK mounting points and an integral “one point” QD sling point on the opposite side of the bolt. The magwell is made to accept both AR15 and MRX supershort magazines. The stock and grip are compatible with standard AR15 furniture.
- The top shroud features a full length picatinny rail for red dots, magnifiers and/or back up sights
- MRX Supershort with three lug bolt offering a 60 degree bolt throw.
- 12.5 inch Steel Barrel finished with Nitride.
- Triggertech Remington 700 Field Trigger

Black Creek Labs has developed a Scout style bolt action rifle that is made to be carried into the backcountry. It is built on a fully aluminum chassis with a steel action and barrel that keeps the rifle accurate, but the overall weight under 7 pounds.
Carrying a smaller, lighter rifle used to mean that you had to trade power or accuracy, but because of the improvements in Black Creek’s manufacturing processes, quality control and the availability of more performance ammunition, the Bison (especially in the Ranger configuration), can outperform many of its heavier and long barreled rivals.
The Bison is easy to carry, easy to handle, faster, more maneuverable and more accurate than most of the rifles in its class. The MRX Bison Scout, with an overall length of 28.5 inches, can easily be thrown over a shoulder, holstered in a rifle scabbard or put into a pack when moving through complex terrain.
Black Creek has designed a modern aluminum chassis to achieve three primary goals. The first goal was to be cost effective. This Chassis was created to keep manufacturing costs to a minimum. The second goal was to ensure a rigid platform that allows for the already inherent accuracy of the MRX action to be complimented. The third goal was to create AR15 modularity by making it compatible with AR15 magazines, grips and stocks
Our collaborative process initiates and inspires unique design ideas. This firearm was designed by the Black Creek team to create a light compact scout rifle that looks and feels like a modern bolt action rifle but with the spirit of a semi-auto. The combination of the aluminum chassis and a simple, modular design gives it a distinguished look that is still highly customizable.
