S7 Tool Steel Internals: Century Arms uses S7 tool steel-the same material used in jackhammer tips-to manufacture the front trunnion, bolt carrier, and feed ramp. This choice aims to maximize high-impact shock resistance where standard cast components traditionally fail. RAK-1 Enhanced Trigger: Unlike gritty surplus AK triggers, the factory-installed RAK-1 trigger group delivers a smooth, predictable break around 5.2 pounds. It is highly regarded for eliminating "trigger slap." Furniture and Aesthetics: The rifle ships in various configurations, including traditional American Maple (often featuring a bright "Russian Red" stain), black synthetic polymer, or a tactical setup featuring a metal triangle stock. Enhanced Safety: The manual safety selector features a built-in notch to hold the bolt open, making range compliance much easier.
