The Rifle Basix RU-T is a precision aftermarket replacement sear engineered specifically for early centerfire Ruger Model 77 bolt-action rifles fitted with the receiver-mounted sliding tang safety. Manufactured from CNC-machined, heat-treated steel with a durable black finish, this component functions alongside the original factory trigger housing, trigger shoe, and sliding safety bar. By replacing the factory sear, it reduces creep and over-travel to provide a crisp, consistent break without requiring permanent alterations to the rifle's receiver.

Key Features

• Direct Interface: Integrates directly with the factory Ruger M77 tang-safety trigger mechanism, preserving the original factory safety operation.
• Adjustable Break: Provides an adjustable trigger pull weight range from 14 oz to 2.0 lbs (approx. 397 g to 907 g) for enhanced field precision.
• Machined Construction: CNC-machined from heat-treated steel to maintain exact engagement surfaces and resist wear.
• Creep Reduction: Significantly reduces trigger creep and over-travel compared to heavy, variable factory sears.
• Mechanical Simplicity: Operates as a completely non-powered mechanical component requiring zero electrical input.

Who is the Rifle Basix Replacement Sear For Rugers With Tang Safety for?

• Owners of vintage Ruger M77 tang-safety rifles — delivers an adjustable pull weight between 14 oz and 2.0 lbs to overcome stiff, inconsistent factory trigger pulls on vintage centerfire actions without modifying the original receiver.
• Hunters and pest controllers — utilizes a precise 14 oz to 2.0 lbs break to reduce creep during field shooting, all while adding just 0.106 lb of total shipping weight to the rifle platform.

Less suitable for: Shooters requiring a pull weight outside the 14 oz to 2.0 lbs envelope—such as heavy hunting triggers above 2.0 lbs or sub-14 oz match assemblies—as well as owners of Ruger rimfire rifles (.22 LR / .17 HMR) or newer three-position wing-safety actions (M77 Mark II, LC6, and Hawkeye), who require platform-specific replacement trigger units.
