Sprinco AR-15 rifle buffer springs are made from high quality Chrome Silicon wire stock. 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 Blue rifle 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.

Note: In an effort to help our customers save on shipping costs, these springs may be shipped without the plastic tube.

    Stock carbine springs and buffers suck. This is an improvement and made things a little more enjoyable. Sprinco quality is great as always.

  2. topgunpilot (verified owner)

    Never wears out and helps slow the bolt down. Too heavy for a Hodge 12.5” barrel with .0645 gas port though.

    Sprinco quality. Threw it in my KAC 14.5 with H2 buffer.
