This is the Browning 10 shot blued steel magazine for the Browning Buckmark rifle and Buckmark pistol.
The magazine features a heat treated steel magazine body, cut out windows on both sides, a U-shaped loading notch in front of the bullet (to avoid case shaving) and is coil spring driven.
Factory replacement parts are manufactured to the exact same specifications and tolerances and use the same manufacturing materials as the standard ones which come with the rifle, ensuring excellent fit and reliable operation.
You can’t go wrong with having extra magazines, whether it’s for quick loading times at the range or in the field. Or, as a backup in case you lose one or drop one in the mud.
