This high performance bolt is manufactured from SAE 9310 steel and boasts a life expectancy of more than 10 times that of a mil-spec bolt. This bolt is for use in a standard Mil-Spec Carrier and uses a standard firing pin, cam pin, extractor and firing pin retaining pin. This bolt features radiuses in all of the traditional 90 degree corners of the locking lug areas. The radiused corners help strengthen the bolt allowing it to handle high loads over a long life span.

Extraction/Ejection fix


I built an LR308 and used a FailZero bcg and was having stove piping double feeds failure to exctract issues researched this bolt and decided to try this before going to a gunsmith and im glad i did i no longer have any og those issues the only thing i notice is that it does leave some marks on the brass but im not going to count that against it
