Sprinco AR-15 buffer springs are made from high quality Chrome Silicon wire stock which is used in a variety of applications from Formula One to motor valve springs which can see up to 15,000,000 compression cycles in a single race.

This makes it the perfect choice for a carbine which will see far less cycles than that over it’s lifetime.

In order for this carbine buffer spring to retain its strength, Sprinco heat treats, shot peens & treats each spring with a proprietary formula that retains spring efficiency for as long as you have your rifle.

The Sprinco M4 Blue Enhanced Power Buffer Spring is a great option to improve the long-term reliability of your AR-15.


  • For carbine-length buffer tubes & mid-length gas systems
  • Color coded blue
  • Enhanced power
  • Made from chrome silicon wire stock
  • Heat treated & shot peened

This recoil spring is color coded blue, indicating that it is optimal for use with 5.56 AR-15s with a mid-length gas system & carbine buffer tube.

Sprinco has extensively tested this setup & have concluded that it works great with 5.56 AR-15’s with a barrel length from 12.5” to 16” & either a standard or H2 buffer weight.

It also helps you to easily identify which power spring you have in your AR-15 if you have a habit of changing your setup constantly.
