This rear sight is engineered as a no-nonsense performance upgrade for Crosman steel breech air pistols in the 13XX and 22XX platforms, including the popular 2240, 1322, and 1377 models. Built for shooters who demand more than the limitations of stock components, this sight delivers a measurable uplift in precision, durability, and overall shooting confidence. Manufactured from solid billet steel—not cast, not polymer—this precision-machined sight offers the structural resilience required for high-repeatability accuracy. Its blued finish delivers corrosion resistance and a clean, professional appearance that aligns with the expectations of advanced hobbyists and tactical airgun modifiers. The design prioritizes integration and fit. The low-profile geometry eliminates the notorious side overhang seen in lower-tier aftermarket sights, resulting in a visually streamlined and operationally stable platform. This ensures consistent sight alignment and improved balance when paired with Crosman's steel breech system. The fully adjustable architecture enables micro-calibrated control. The elevation-adjustable blade (.050” wrench required) allows shooters to tailor point-of-impact across varied distances or ammunition types. Windage adjustment is facilitated through a precision dovetail interface secured by a 5/64” set screw, ensuring firm lockup and dependable repeatability shot after shot. Designed exclusively for Crosman steel breeches, this sight does not fit plastic breech systems or earlier vintage models. Dimensions are optimized at 3.0" x 3.0" x 1.0" for a clean, compact footprint. Allen wrenches are not included by design, allowing users to utilize their preferred tools. For shooters, builders, and modders committed to upgrading their platform with materials and machining that exceed factory-grade standards, this billet steel rear sight reflects a forward-thinking approach to accuracy, reliability, and system integrity. Note: This sight is exclusively compatible with steel breeches and will not fit stock plastic breeches or vintage Crosman firearms. Allen wrenches for adjustment are not included.
