LBE Unlimited ARSPRG AR Parts Carbine Length Recoil Spring AR-15 Silver

The LBE Unlimited ARSPRG is a drop-in carbine length recoil spring designed for use with the AR-15 carbine receiver extension. As a direct replacement for the factory buffer spring, this component is an essential maintenance item for any AR-15 owner running a standard carbine buffer setup, ensuring the bolt carrier group cycles reliably under recoil.

Manufactured from high-quality 17-7 stainless steel, this recoil spring delivers consistent tension and corrosion resistance suitable for hard-use rifles and builds exposed to the elements. The dimensions are matched to the standard carbine buffer system, and the silver finish presents a clean, factory-style appearance that pairs well with most buffer tubes and stock assemblies.

Installation is simple: remove the carbine stock, pull the factory buffer spring out of the receiver extension, drop in the new ARSPRG spring, reinstall the buffer, and replace the stock. Proudly made in the USA, this is a must-have replacement spring for routine AR-15 maintenance or any fresh build.
