Lets You Load Mags Fast Without A Sore Thumb

Fast, painless way to load Ruger® rimfire magazines: “latches” to the loading button and bottom of the mag to keep the spring and follower compressed. Eliminates the need for constant thumb pressure to keep the follower retracted, so you can load more magazines faster—without a sore thumb afterward. Ambidextrous design provides a non-slip grip for right- or left-hand loading. Constructed of durable, reinforced nylon polymer for long-lasting reliability.
