Sprinco M4 / AR-15 Blue Enhanced Power Buffer Spring

The Sprinco AR-15/M4 carbine buffer springs are crafted using premium Chrome Silicon wire, a material commonly used in high-performance applications such as Formula One racing and motor valve springs. With the potential to withstand up to 15,000,000 compression cycles in just one race, this wire stock is an ideal choice for a carbine that will experience significantly less wear over its lifespan. To ensure the longevity of these springs, Sprinco employs heat treatment, shot peening, and a special formula that enhances their durability for the entire lifetime of your carbine. Opting for the Sprinco Blue carbine buffer spring is a smart move to enhance the long-term dependability of your AR-15/M4.

The carbine length buffer tubes and mid-length gas systems play a crucial role in the overall functioning of an AR-15/M4. To enhance the performance of these components, Sprinco has introduced a color coded blue recoil spring, made from chrome silicon wire stock that has been heat treated and shot peened. This particular spring is designed for use with 5.56 AR-15s with a mid-length gas system and carbine buffer tube, making it highly efficient for barrel lengths ranging from 12.5″ to 16″. Additionally, its enhanced power allows for optimal operation with both standard and H2 buffer weights. The blue color coding serves as an easy identifier for users who frequently switch between different setups, ensuring maximum compatibility and performance.
