AR-15 and AR-10 Pins & Springs for Builds and Repairs
This category covers the small hardware that keeps an AR build functioning: detent springs, retainer springs, fire control springs, and pins for both AR-15 and AR-10 platforms. You'll find the bolt catch detent spring, buffer retainer spring, disconnect spring, hammer spring, magazine catch spring, pivot and takedown pin spring, safety selector and ejector spring, and trigger spring, along with the buffer retainer pin and fire control group pin.
Most items ship in ten-packs, making them practical for builders maintaining multiple rifles and shops handling repeated assemblies. These American-made, mil-spec parts suit beginners assembling a first lower, gunsmiths restocking common wear items, and manufacturers sourcing components. When selecting, confirm platform compatibility, identify the function each part serves, and account for quantity needs.
Round out your build with build kits, trigger parts, and detents.
