The Leupold Dual Dovetail T/C Contender 1-Piece Handgun Base (Gloss Black), manufacturer part number 53556 (also referred to as model LE53556), is a precision-engineered optical mounting platform designed specifically for the Thompson/Center Contender handgun and rifle platform. Manufactured from forged and machined steel, this one-piece base provides a secure foundation for mounting optics on firearms that experience substantial recoil. The gloss black finish delivers a classic look that integrates cleanly with polished factory firearm finishes. By utilising Leupold's twist-and-lock Dual Dovetail system, this base eliminates the traditional rear windage screws, creating a highly rigid connection that keeps your scope securely zeroed under demanding field conditions. Key features of this mounting base include:

• Dual Dovetail System: Utilises a secure twist-and-lock mechanism on both the front and rear rings, removing the weak point of rear windage adjustment screws.
• Recoil Resistance: Engineered specifically to withstand the heavy, sharp recoil associated with large-calibre and magnum-chambered T/C Contender handguns.
• Low-Profile Profile: Keeps the optical axis close to the barrel bore line, improving eye-to-scope alignment and overall shooting ergonomics.
• All-Steel Construction: Machined from forged steel to ensure long-term durability and structural integrity under repeated firing.
• Passive Design: As a fully mechanical accessory, it requires no batteries or electrical power, making it exempt from Australian Regulatory Compliance Mark (RCM) or SAA electrical safety approvals.

This optical mounting base is designed for target shooters, handgun hunters, and metallic silhouette competitors in Australia who demand absolute stability from their Thompson/Center Contender platforms. It is ideal for those shooting heavy-recoiling cartridges where standard mounting systems might slip or lose zero over time. While this product is a passive firearm accessory and is not classified as a major controlled firearm component under Australian state laws, customers should always ensure compliance with their local state or territory police regulations regarding the importation and installation of firearm accessories.
