The LMT .308 Extractor Spring is a small, but important part of your bolt carrier group. This spring is responsible for extracting spent brass from the chamber after firing a round. It is easily confused with detent springs, so be sure to keep them separate when assembling your rifle.
This small part is an essential component of your bolt carrier group and should be regularly checked and cleaned. The LMT extractor spring is made from high quality materials and is backed by a lifetime warranty. Test fire your rifle at a range before taking it to a competition to ensure proper functioning.
