Weaver 48111 Top Mount Base 406S Silver - TCA Thunderhawk Scope Mount

The Weaver 48111 Top Mount Base 406S delivers rock-solid scope mounting for TCA Thunderhawk muzzleloaders with precision-machined aluminum construction. This silver-finished base transforms your Thunderhawk into a long-range hunting platform capable of consistent accuracy at extended distances.

What Makes This Different

Unlike generic scope bases that require gunsmithing modifications, the Weaver 48111 mounts directly to the TCA Thunderhawk's factory-drilled receiver holes. The 406S configuration provides optimal eye relief positioning for muzzleloader scopes, accounting for the unique sight picture requirements of black powder hunting. Precision CNC machining ensures perfect ring alignment, eliminating scope cant that plagues inferior mounting systems.

Key Features

• Direct bolt-on installation for TCA Thunderhawk receivers - no drilling required
• Precision-machined 6061-T6 aluminum construction with silver anodized finish
• Weaver-style cross slots accept standard 1-inch and 30mm scope rings
• 406S spacing optimized for muzzleloader scope eye relief requirements
• Four mounting screws included with thread-locking compound pre-applied
• Low-profile design maintains iron sight compatibility
• Corrosion-resistant finish withstands harsh hunting conditions

Field performance remains consistent across temperature extremes and heavy recoil cycles typical of magnum muzzleloader loads. The rigid aluminum platform maintains zero through multiple shooting sessions, critical for hunters working up loads during the off-season. Hunters report maintained accuracy at 150+ yards when paired with quality optics, extending effective range significantly beyond iron sight capabilities.
