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.

Noticeable more when charging the weapon than during firing. Didn’t change ejection pattern much, if at all when testing between 2 lowers, same upper. Yet to try it for my overgassed noveske recon chf barrel—but I might have to step up to a red-white or red sprinco.
