Brownells Detent Ball Refill 1/16" Diameter (1.6mm) 20-Pack

The Brownells Detent Ball Refill is a pack of 20 precision steel detent balls measuring 1/16" (1.6mm) in diameter. Designed for gunsmithing applications, these small detent balls are commonly used in firearms assembly and repair where spring-loaded detents retain pins, levers, or selector components. Having a ready supply on hand is essential for professional gunsmiths and home builders to avoid losing these small but critical parts during disassembly.
