One from Grade 6 Titanium and the other from 17-4 Stainless Steel Heat Treated to H900 Condition. Material certification will be sent with Titanium pin!!! These are brand new and designed to fit most AR-15, SR-15, M16. Using our in house CNC Swiss turning centers the AR-15 Firing pins are machined from the best of both worlds. Stainless for great strength and titanium for ultral light and fast action. Get both for a great price. Note: Titanium is not as strong as steel thus the life of the pin is not determined. We are estimating 3000 rounds prior to replace. However, this Grade 6 of titanium is 50% stronger than Grade 2 which almost doubles the material strength.
