BCL MRX Bison 20 Round Magazine



The MRX Bison is the only rifle in the world that feeds from both a proprietary 20 round bolt action magazine and an AR15 magazine. The ability to function with any AR15 magazine gives the user an almost infinite number of options for magazine brands, capacity, material and style. Alternatively, “The MRX MAG†gives the user a 20 round capacity in a magazine that is specifically designed for the MRX Supershort Action and will not fit or function in an AR15 or any other semi-auto rifle.

The MRX MAG is a double stacked, straight magazine made from a proprietary blend of polymer. The MRX MAG has extended length feed lips and a no-tilt follower design that allows ultra smooth and reliable feeding. The MRX MAG uses “follower stop ledges†which keeps the follower from topping out, which allows the MRX Supershort bolt to be manually pushed forward when the magazine is empty and still in the rifle, which is not possible with an AR15 magazine.
