This is the 3 round .300 Win Mag magazine for the Browning BLR.
This magazine will fit all post 1981 BLR models. It will not fit pre 1981 models. You can identify which model you have from the bolt design in our technical photo.
Browning moved to an AR-15 style rotating bolt in 1981, which locks into the barrel and allowed use of an alloy receiver. They no longer support the pre-1981 design, which are rare finds second hand.
Made from blued steel this factory replacement magazine is a double stack design with a stainless follower.
