This is a Magnum Research Magnum Lite .22LR Magazine with a 10-Round Capacity.
With durable, lightweight construction and a reliable rotary design, this Magnum Research magazine is the perfect accessory for your Magnum Lite rifle.
Rugged polymer construction reduces weight and boosts durability. The rotary design allows for a full 10-rounds to be stored in a flush-fitting profile, preventing the magazine from protruding from the rifle and creating a snag hazard.
The rotary design also promotes reliability and provides smooth feeding round after round.
