The Sprinco Yellow Reduced Power Carbine Buffer Spring is a high-quality buffer spring made from ASTM Grade A877 certified valve-quality chrome silicon wire stock. It's heat treated, stress relieved, and dual-stage shot peened post-winding for maximum durability and performance.
Features:
- For carbine-length buffer tubes
- Color coded yellow
- Reduced power, approximately 20 percent lighter than the White spring
- ASTM Grade A877 certified chrome silicon wire stock
- Heat treated, stress relieved, dual-stage shot peened
The Yellow spring offers consistent spring pressure through its full cycle, resulting in fewer malfunctions related to spring operation, especially Type III malfunctions, along with improved resistance to heat-induced performance degradation compared to other buffer springs. Correct spring selection works reliably and virtually indefinitely in a properly built and maintained AR platform, reducing the need for spring replacement over the service life of the upper receiver.
Sprinco USA manufactures precision recoil springs using the same chrome silicon wire stock trusted in Formula One and motorsport valve springs, engineered to retain their spring rate far longer than a standard AR-15 buffer spring.

Fix for 13.7 w/ mid length gas
by Ryan
I have a 13.7 middy that was under gassed just enough to not fully cycle sub par ammo. Most of the time it would cycle but never lock back on last round. Could’ve just stuck with the milspec spring and only use quality ammo but I want all my rifles shooting any type of ammo, just my preference. Threw the yellow in and it ejects rounds at 4 and cycles perfect.
Reduced Power spring
by Grendelman -
I ordered this spring to help with the ejection of a 5.56 pistol. It was denting the front of the case mouth as it would eject the round and would not reload the next one. I equipped it with standard parts as this was my first pistol build. I used an 8in Faxon barrel with a 3oz buffer and standard buffer spring. Turns out the Faxon barrels are equipped with smaller gas ports requiring lighter weighted parts such as this spring. This was the only thing I had to replace, and it works flowless now. Great product with great resalts. I highly recommend this to anyone using a Faxon pistol barrel.
