Sprinco Buffer Springs – AR-15 / AR-10
Color-Coded Precision for Ultimate Reliability
Sprinco buffer springs are built for durability and performance using ASTM Grade A877 certified Chrome Silicon wire stock—the same material trusted in Formula One valve springs. Each spring is heat treated, shot peened, and treated with Sprinco's proprietary formula, ensuring consistent performance and long-term reliability in any AR build.
Whether you're tuning a suppressed SBR, balancing a mid-length gas system, or running a heavy-hitting AR-10, Sprinco offers the perfect power level—clearly color-coded for easy identification and quick swaps.
Note: All springs weigh approx. 0.75 oz and are made in the USA.
White – Standard Power
For 5.56 carbines; ideal with carbine gas and H2 buffer (e.g., 10.5" SBRs).
Red/White – Intermediate Power
For carbine or mid-length gas; softens recoil and improves timing.
Blue – Enhanced Power
For 12.5"–16" mid-lengths; improves cycling with standard or H2 buffers.
Red – Extra Power
Best for 16" carbine gas or calibers like .458 SOCOM, 6.5 Grendel.
Yellow – Reduced Power
~20% lighter than White; ideal for reduced recoil builds and cycling control.
Green – Standard Rifle Spring
For rifle-length gas systems (A2 stocks, VLTOR A5); tested for stability and consistency.
Orange – Extra Power
Tuned for .308 ARs with carbine buffer tubes; handles over-gassed setups
