Sprinco M4 Blue Enhanced Power Buffer Spring

$19.95

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, and treats each spring with a proprietary formula that retains spring efficiency for as long as you have your rifle. The Sprinco enhanced power carbine buffer spring is a great option to improve the long-term reliability of your AR-15.

Features:

  • For carbine length buffer tubes and mid-length gas systems
  • Color coded blue
  • Enhanced power
  • Made from chrome silicon wire stock
  • Heat treated and 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 and carbine buffer tube. Sprinco has extensively tested this setup and have concluded that it works great with 5.56 AR-15’s with a barrel length from 12.5” to 16” and 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.
