The RPC blends proven ergonomics with modern capability, thanks to its roller-delayed operating system that both enhances reliability and reduces felt recoil. The aluminum construction trims weight while maintaining duty-grade durability. Controls are fully ambidextrous, with the bolt release/lock and magazine release easily reached from both sides, and a reversible, non-reciprocating charging handle that adapts to the shooter, not the other way around.
