The Iver Johnson Model 2X in .22 Short/Long/LR is a vintage single-shot bolt-action rifle with a 23.5-inch (or typically listed as 24-inch) barrel and 1-round capacity, designed as a lightweight, affordable "self-cocking safety" plinker and youth/trainer gun from the 1930s to 1950s. Produced by Iver Johnson's Arms & Cycle Works, it features a unique patented automatic safety mechanism integrated with the bolt (which cocks on closing and has a distinctive rotating handle for safe handling), thumb-screw takedown for easy cleaning, adjustable rear sights, a post front sight, blued finish, checkered pistol-grip walnut stock with finger grooves, and chrome-plated bolt and trigger for smooth operation. Weighing around 4.5 pounds unloaded with an overall length of about 41 inches, it offers minimal recoil, reliable rimfire performance across all three .22 lengths, and classic simplicity-making it a fun, collectible piece for plinking, small-game hunting, or nostalgic shooting that's still appreciated by enthusiasts for its quirky design and solid build quality.
