If you’re running an SBR or AR-15 pistol, you know that reliability can sometimes be an issue. With the BCM AR-15 Extractor Spring Upgrade Kit, you can easily make your AR extract properly and consistently. The heavy coil extractor spring is designed to increase the extractor tension, so that it will overcome the harsher recoil of a short gas system and reliably extract spent cases.
This spring is manufactured from high quality chrome silicon material and is heat treated and shot peened to improve strength. Also included in this kit is the improved black extractor insert as well as an O-Ring.
