The Sons Of Liberty Gun Works XP Extra Power Rifle Buffer Spring is engineered for shooters who want consistent, dependable cycling from their AR-pattern rifles. Built from 17-7 passivated stainless steel and finished in a black color code for quick identification, this spring delivers roughly ten percent more force than a standard rifle-length spring, helping regulate bolt speed and enhance reliability in demanding setups.

This XP spring is purpose-built for A5/intermediate and rifle-length buffer systems, making it a strong choice for suppressed rifles, high-pressure loads, or duty-style builds that see high round counts. By maintaining tension and resisting corrosion over extended use, it supports smoother operation and reduced wear on internal components. Sons Of Liberty Gun Works is known for producing durable, no-nonsense parts that integrate seamlessly into most mil-spec platforms.
