Century Arms RI4378N VSKA Trooper | 7.62×39 | 16.5″

The Century Arms RI4378N VSKA Trooper is an AK-style semi-automatic rifle chambered for 7.62 x 39mm, fitted with Magpul MOE furniture and an Ultimak rail-style handguard. Its 16.50″ 4150 chrome-moly barrel and flash hider reflect the platform’s emphasis on proven durability and common AK ergonomics. This rifle suits range-focused shooting and medium-game field work where robust, readily available ammunition and straightforward maintenance are priorities. A versatile optic pairing under $1,000 is a low-power variable (for example, a 1–4x or 1–6x scope such as the Vortex Crossfire II 1-4×24) mounted to the Ultimak rail for quick target acquisition and durability.
