The LWRC Advance Combat Bolt for 6.8 SPC fits into any mil-std bolt carrier and functions perfectly. It has a full support face that lacks the two undercuts on either side of the extractor pocket that weaken traditional bolts. The bolt is machined from a super-alloy steel that is designed to take extreme loads without failure, and shot-peened for enhanced durability. A dual spring extractor design increases extraction force and triples the service life. The bolt is nickel boron coated for a lower coefficient of friction.
