Sons of Liberty Gun Works Extra Power Rifle Buffer Spring Black

The Sons of Liberty Gun Works Extra Power Rifle Buffer Spring is an AR-15 replacement buffer spring designed for A5 intermediate and rifle length buffer tubes. It is intended for builders who want additional spring force to help return the bolt carrier group forward, which can aid cycling in rifles that run slightly under gassed or use heavier buffers.

The spring is made from 17-7 passivated stainless steel, a material chosen for corrosion and fatigue resistance over repeated compression cycles. It has a black finish that makes it easy to tell apart from a standard power spring during maintenance or when swapping components between builds.

Because it fits common mil-spec rifle length and intermediate buffer systems, it suits builders already familiar with AR disassembly. It is often paired with an adjustable gas block or used in suppressed configurations.
