Take-Up Spring 7in Long

The LANDRUM SPRINGS Take-Up Spring 7in Long (part number TU7X5) is a precision mechanical spring engineered for firearm trigger mechanisms and assemblies where consistent spring force and repeatable performance are critical. This 7-inch take-up spring delivers the controlled tension required in trigger groups, bolt catch systems, and other mechanical assemblies where predictable engagement and reset are non-negotiable.

Manufactured by LANDRUM SPRINGS, a recognized supplier of precision coil springs for firearms and mechanical assemblies, this take-up spring is designed to maintain its spring rate across extended use cycles. The 7-inch length accommodates mid-frame and receiver-mounted installations where longer spring travel is required. At 0.7 lbs, the spring is lightweight while maintaining the wire diameter and coil pitch necessary for reliable mechanical function. Specification-grade construction ensures the spring delivers consistent force delivery from first round downrange through service life, minimizing the variation that causes felt inconsistency or intermittent engagement issues.

Gunsmiths, armorer-level builders, and platforms undergoing trigger group customization or repair rely on replacement springs like this where OEM or upgraded components require a matching take-up spring. This 7-inch version suits rifle platforms, precision assemblies, and systems where stock or aftermarket trigger mechanisms need a verified spring replacement. Verify fitment against your specific platform and spring pocket before purchase, as take-up spring length and rate must match the exact mechanism design for proper function and safety.

Stock-sourcing replacement springs from established manufacturers like LANDRUM ensures you receive a spring with consistent coil geometry, proper heat treat, and predictable performance—critical factors in trigger mechanisms where inconsistency creates reliability gaps or unsafe conditions.
