This is the Triple K 10 round .22LR magazine for the Weatherby XXII semi-auto rifle.
Not suitable for Anschutz made Weatherby XXII bolt action rifles, which use the Anschutz 64 action, please see our compatible Anschutz 1400 series magazines.
The original XXII semi-auto rifles and magazines were produced under contract by three manufacturers, Beretta (Italy) in the 1960s, Nikko (Japan) in the 1970s and Mossberg (USA) in the 1980s, discontinued in 1990.
Early magazine models from Beretta have a rear grove for the magazine catch, later Japanese models have a square locking catch hole. This magazine has both.
Manufactured from blue steel. Strippable for cleaning.
