A high-capacity magazine, often cylindrical in shape, designed for the Ruger 10/22 rifle, capable of holding 100 rounds of .22 Long Rifle ammunition, combined with a modification enabling fully automatic fire. This configuration allows for sustained firing without reloading, significantly increasing the firearm’s rate of fire.
The large ammunition capacity offers a distinct advantage in certain shooting disciplines, such as competitive events requiring rapid target engagement. Historically, similar high-capacity systems have played roles in various military and civilian applications, though their use is often subject to specific regulations. The modification to enable fully automatic fire significantly alters the weapon’s operation, demanding careful handling and adherence to legal requirements. The Ruger 10/22 platform, known for its versatility and reliability, provides a common foundation for such modifications.
