Browning Double Helix Magazine for .17 HMR and .22 Winchester Magnum Rimfire 10 Round

Uses a torsion drive spring and interlocking gear design to maintain correct timing and exact cartridge alignment. Translucent gray body. Ammunition can be removed by moving the exposed gear back slightly. Twin gripping grooves, tapered shape and a slightly extended baseplate design make insertion positive while the spring-assisted drop-free magazine ejection feature allows for rapid magazine changes.
