Overview
The Armaspec Stealth Buffer Spring is a captured spring designed specifically for the AR-15 platform. This type of spring helps ensure consistent operation and reliability by minimizing the potential for spring bind and enhancing the overall cycling of the action. You'll often find this spring in builds with a mid-length gas system and chambered in 5.56 NATO, where smooth performance is essential.
