Black Creek Labs MRX Bison Scout Rifle

In stock

The MRX Bison is a compact, light and rugged bolt action rifle that is chambered in 5.56x45mm and is fed with AR-15 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.  In addition to being compatible with AR-15 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 AR-15 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 AR-15 and MRX supershort magazines.  The stock and grip are compatible with standard AR15 furniture.

MRX Supershort with three lug bolt offering a 60 degree bolt throw.

Match Grade Steel Barrel finished with Nitride.

TriggerTech Remington 700 Primary Trigger.
