SPRINCO

Sprinco springs are manufactured from Chrome Silicon wire. Chromium-silicon alloy is noted for its hardness and superior performance at extremely high stresses. Because of its heat resistance and hardness, the alloy can be used in valve springs and automatic transmissions at temperatures over 275 degrees Fahrenheit. Chrome-silicon was originally developed for recoil springs in anti-aircraft guns where high resistance to shock loads and long life is needed. The endurance limit of Chrome-silicon either before or after shot peening equals that of carbon steel in the same condition. At a given stress value, it can be used at a temperature 100 degrees Fahrenheit higher than Chromium-vanadium and higher hardness without breaking. This alloy provides excellent service for applications in the 5,000 to 50,000 cycle ranges. Available in a sensible range of popular weights, professional shooters and manufacturers who have tested our springs attest to the fact that our springs meet and maintain spec performance better than any other recoil spring on the market today. We perform the Cryogenic Processing of our springs in-house using state of the art equipment.

TACTICAL SPRINGS (SPRINCO) AR-308 EXTRA POWER BUFFER SPRING - ORANGE

$19.95 Price

"ORANGE Spring" The ONLY specifically engineered EXTRA POWER Buffer Spring for .308 Carbine Platforms using standard 7" Depth M4 extension tubes and .308 short 2.5" buffers (Including aftermarket "heavy buffers.") You cannot clip coils from any other commercially available buffer spring to yield the proper spring loads for this application, especially in heavily gassed .308 carbine platforms. Sprinco started from scratch on this design to provide Operators with a viable alternative to existing OEM and aftermarket offerings. Platforms known to exist using this approach include Arms Industries, DPMS, Bushmaster (Post 2010), Remington, CMMG, Mega, SA Defense, Colt 901, Rock River Arms and many others.
