Sprinco Orange Extra Power Spring

The Sprinco Orange Extra Power spring represents the most aggressive buffer spring option for AR-15 carbines facing extreme overgassing conditions. Originally engineered for .308/6.5 Creedmoor/.260 Remington heavy bolt carrier group DPMS pattern applications, the Orange spring has found a niche in robustly gassed 5.56 carbines where even the Blue enhanced power spring proves insufficient. With significantly stouter spring loads than the Blue, the Orange spring delivers maximum resistance for taming violent gas systems on short-barreled rifles, oversized gas ports, or hot ammunition loads.

Constructed from the same ASTM Grade A877 certified valve quality chrome silicon wire as other Sprinco springs, the Orange undergoes identical heat treatment, stress relief, and dual-stage shot-peening processes. This ensures the heavier spring maintains proper tension over extended service life without taking a set or losing its enhanced power characteristics. The Orange spring proves most effective on 16-18 inch mid-length gas carbine platforms yielding solid 1:30 to 2:00 o'clock ejection trajectories, where it can be fine-tuned with appropriate buffer weights.

The Sprinco Orange represents a specialized solution for specific problem systems rather than a general-purpose upgrade. Shooters should exhaust other tuning options—proper gas block adjustment, H2/H3 buffers, restrictive gas tubes—before resorting to the Orange spring's extra power. When properly applied to extremely overgassed systems, however, the Orange spring effectively controls bolt carrier velocity while maintaining reliable extraction and ejection. Pairing the Orange with appropriate buffer weights creates a robust solution for the most challenging gas tuning scenarios.
