Sons of Liberty Gun Works Extra Power Rifle Buffer Spring Features The Sons of Liberty Gun Works Extra Power Rifle Buffer Spring is designed to work with A5 intermediate and rifle length buffer systems giving builders flexibility across several common AR configurations. Delivering roughly 10 percent more force than a traditional rifle length spring it helps push the bolt carrier group forward with added authority which can improve reliability in rifles that run slightly under gassed or that use heavier buffers. Constructed from 17-7 passivated stainless steel the spring resists corrosion and fatigue over repeated cycles of compression. This material choice supports a longer service life compared to a basic carbon steel spring under the same round count. The spring is finished in black making it easy to visually distinguish from a standard power spring during maintenance or when swapping components between builds. Because it is built to fit most mil spec rifle length and intermediate buffer tubes installation is straightforward for builders already familiar with AR disassembly. An extra power spring like this is often used alongside an adjustable gas block or in suppressed configurations where additional spring force helps manage the extra energy in the system. This small focused upgrade gives shooters a simple way to fine tune cycling reliability on a rifle length AR build.
