Alexander Arms RTA65DE | 6.5 Grendel | Flat Dark Earth Cerakote

It is configured with an M-LOK handguard, Picatinny rail on the receiver, B5 Bravo synthetic stock and an A2-style grip; the package also lists a Mil-Spec trigger and an A2 flash hider. For a practical optic that stays well under $1,000 and pairs with this platform, consider the Vortex Viper PST Gen II 1-6×24 for fast target acquisition and reliable mid-range performance.
