BCL MRX Bison Scout 5.56 NATO 12.5″

The Black Creek Labs MRX Bison is a compact, light and rugged bolt action rifle that is chambered in 556N, 300 Blackout and 7.62X39.  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 AR15 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 MRX Mags.  The MRX Mag is a proprietary 20 round bolt action 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.  The Bison sits in an aluminum, monolithic chassis and is available with 12.5 inch and 16.5 inch barrels.

The BCL MRX Bison Scout 5.56 NATO 12.5″ action rifle is an excellent choice for hunters looking for a reliable and accurate firearm. With its 12.5″ barrel and compact design, this rifle is easy to maneuver in tight spaces and offers excellent accuracy at a distance. The MRX Bison Scout is built with high-quality materials and features a free-float handguard, ambidextrous controls, and a reliable gas piston system. Whether you’re hunting in the bush or stalking game in the mountains, the BCL MRX Bison Scout is a versatile and dependable rifle that won’t let you down.

    Excellent Scout Rifle!

    This rifle is very well designed. The fit and finish is excellent, the ergonomics make it comfortable to shoot and the manual of arms is familiar. Out of the box, this rifle is dead nuts reliable and very accurate.
