The EGW Scope Base WIN 52 is a precision-made foundation designed to upgrade Winchester 52 target rifles with a durable black matte aluminum alloy Picatinny rail, delivering consistent alignment and repeatable performance in the field or at the range. Engineered to accept Mil-STD 1913 Picatinny rings, this base provides a secure, versatile mounting platform that supports a wide range of optics while maintaining strict tolerances for accurate shot placement. Its compact footprint measures 0.95 x 3.35 x 8.05 inches, offering a low-profile profile that preserves sightlines and balance without adding unnecessary bulk. Built to endure demanding shooting conditions, the alum alloy construction resists deformation under recoil, ensuring repeatable return-to-zero after each shot. The Black Matte finish minimizes glare and enhances durability against wear from handling, cleaning, and exposure to the elements. While designed for Winchester 52 targets, the EGW scope base is a practical upgrade for shooters seeking a reliable, consistent mounting solution that aligns optics precisely with the bore axis. With no rings included, this base invites the user to pair it with their preferred high-quality rings to achieve an ideal setup for field positions, benchrest accuracy, or competition shooting.
