Spro USA

Overview

The Sprinco USA Reduced Power Kit Buffer 4-Coil Bolt Extractor Spring is designed to provide a lighter extraction force for your bolt carrier group, which can improve reliability in certain builds. By reducing the spring tension, this component allows for smoother operation, particularly in systems where a lighter buffer is preferred. This spring is commonly found in pistol builds chambered in 5.56 NATO, where enhanced cycling and reduced recoil can be beneficial.
