The A-Bolt and A-Bolt II still own an incredible reputation for accuracy and functional perfection. Often a costly upgrade to other factory rifles, extra magazines have been a standard feature on Browning big game rifles for decades. Having an extra loaded magazine in your bag or pocket while hunting is undoubtedly better than a pocket full of loose shells mixed in with your truck keys and that half-eaten granola bar you were saving for later.
Historically there have been three versions of bolt actions that have at times been referred to as A-Bolts. This magazine fits only original A-Bolt and A-Bolt II rifles. Not the AB3 (sometimes called the A-Bolt III). This is a genuine Browning replacement part.
