The LBE Unlimited AR-15 buffer retaining spring 10-pack keeps a critical component of your AR-15 operating system in place. The buffer retaining pin spring is a small but essential part that holds your buffer retaining pin securely, preventing it from walking out during firing cycles or disassembly. Whether you're building your first AR, maintaining a range gun, or stocking spare parts for an armorer's kit, having a fresh supply of these springs on hand means you're never stuck mid-project or forced to improvise with worn hardware.
These springs are manufactured in the USA, reflecting LBE Unlimited's commitment to domestic production. The 10-pack format makes sense for anyone who builds or maintains multiple rifles, runs a club range, or simply prefers to keep common wear items in stock. Springs can fail or be lost during field stripping and cleaning, so buying in bulk is practical insurance.
LBE Unlimited has built a reputation among AR builders and gunsmiths for producing reliable, no-nonsense parts that work. This spring fits the standard AR-15 buffer retaining pin assembly, making it a straightforward replacement or spare for any mil-spec or commercial-spec receiver you're working with.
