The Geissele Stress proof Bolt is proudly featured in their Reliability Enhanced Bolt Carrier Group. The Forged Stress proof Bolt is made from Carpenter 158+, developed directly with Carpenter Steel metallurgists to produce a cleaner material with fewer impurities. This makes the Stress proof Bolt stronger and more fatigue-resistant, capable of 5 times the life of a mil-spec bolt. Each Forged bolt is rigorously inspected, high-pressure tested, mag particle inspected, and Nano weapon coated.
