Our Phosphate coated C158 Bolts come standard with Ejector Springs, Extractor Springs, O-Rings, and Gas Rings (x3) made by Sprinco. This is done to ensure your rifle will extract and eject casings reliably over time. We are also impressed with the increased life of Sprinco's gas rings. Sprinco is known for their quality components that outlast milspec counterparts. For example, shorter ARs and suppressed ARs can beat the hell out of gas rings. Generally, the rings will wear out in approximately 3 to 4 thousand rounds in shorter and suppressed guns. The Sprinco gas rings have shown they can perform and last for approximately 8 thousand rounds.
 
Every Ripcord Bolt is high pressure/proof tested and is available with or without a Nitride-Coated FCD SOTAR Cam. 
 
Whether you're needing spare parts on hand, or replacing a worn out bolt, our mil-spec style bolt is a solid part to have.  
 
Points to inspect on your bolt during routine maintenance are;
Both sides of the bolt body (either side of the hole) where the cam pin is inserted. Ensure there are no cracks forming.
The lugs of the bolt, especially on either side of the extractor. Look for unusual wear or cracks. 
The extractor itself and its spring assembly. The "claw" of the extractor should be checked for build-up and should feel somewhat like a cat's tongue. If you are experiencing failure to extract malfunctions repeatedly, your extractor spring, the extractor itself, or both may be worn out. 
Headspace should be checked approximately every 5K rounds. Ensuring your AR is headspaced will help the gun operate efficiently. It also reduces the rate at which various parts wear out.
