The Lyman Deerstalker Right Hand Sear (SKU: LY-DSRHS) is a critical, precision-machined internal lock component designed to maintain the safety and mechanical integrity of your muzzleloading rifle. Manufactured in partnership with Investarm in Italy, this replacement sear serves as the vital mechanical linkage holding the rifle's hammer or tumbler under spring tension at both the half-cock and full-cock positions. When the trigger is pulled, the sear releases the tumbler, allowing the hammer to strike the percussion cap or frizzen to ignite the black powder charge. For Australian black powder shooters, keeping this high-wear component in top condition is essential for ensuring reliable ignition and safe operation in the field or at the range. Key Features:

• High-Tensile Construction: Crafted from precision-cast and hardened steel to resist wear, chipping, and friction over repeated cocking cycles.
• Critical Safety Function: Restores the positive engagement of the half-cock and full-cock safety notches, preventing accidental discharges.
• Smooth Trigger Release: Provides a clean surface interface for the trigger assembly, which can help reduce creep and assist in trigger tuning.
• Genuine Factory Fit: Engineered to exact tolerances to drop directly into standard right-handed Investarm and Lyman lock plates.
• Dual Ignition Compatibility: Performs flawlessly in both percussion cap and traditional flintlock ignition systems.

Who It's For:

If your rifle's hammer is slipping, failing to hold at half-cock, or experiencing a heavy, inconsistent trigger pull, this replacement part is the ideal solution to restore factory-standard safety and performance. It is a highly sought-after component for shooters servicing Lyman or Investarm side-lock rifles in New South Wales, Victoria, Queensland, and other states. Please note that while this is a non-powered mechanical spare part, owners should always ensure compliance with their local state or territory firearm regulations regarding the maintenance and repair of firearm action components.
