The Upper Spring Cup LW Steel is a precision-engineered buffer tube component designed specifically for AR-pattern rifles and tactical platforms that require reliable spring retention and recoil management. This lightweight steel spring cup is essential for shooters who demand repeatable accuracy and consistent cycling of the bolt carrier group.
Constructed from hardened steel with a durable black powder coat finish, the Upper Spring Cup LW Steel serves as the critical interface between your buffer spring and lower receiver assembly. Its screw-on attachment design eliminates the need for proprietary tools during installation or disassembly, making it user-friendly for those familiar with firearm assembly.
This upper spring cup is ideal for gunsmiths, armorer-level shooters, and tactical rifle builders who service or assemble their own platforms. Its lightweight designation helps reduce overall receiver extension weight without sacrificing durability, making it a valuable addition for precision rifle and carbine setups.
