The Optimized Carrier Key Screws (OCKS) are designed to provide significant advantages over the standard cap screw used in carrier keys.
Proper staking is crucial to reliable operation. An improperly staked carrier key can become loose under firing, and can cause a debiliating malfunction that can render a firearm inoperable in the field. The OKCS has sharp, deep, and effective knurling with 12 deeper splines. These OCKS allow for metal to flow into the space when staking, creating more metal on metal contact.
Available as upgrade option on all RCA BCGs/Carrier Assemblies or purchased separately for an existing BCG/Carrier Assembly.
