Let’s Dive into SIG SAUER Fps Spring

The SIG SAUER Fps Spring, a seemingly small but crucial component, plays a vital role in the reliable function of your SIG Sauer MCX rifle. This unassuming steel spring, manufactured by SIG SAUER, ensures proper firing pin movement. It retails for $16.99, which positions it as a relatively inexpensive, yet essential, replacement part.
