KelTec RDB, 5.56 NATO / .223 Rem, 20″ Barrel, 20+1 Capacity, FDE Rifle

Features and Performance

The KelTec RDB, 5.56 NATO / .223 Rem, 20" Barrel, 20+1 Capacity, FDE Rifle puts KelTec’s unconventional design language into a rifle with 5.56 NATO / .223 Rem, 20" barrel, 20+1 capacity, FDE, giving it a clear role for compact bullpup rifle handling, range use, and field-ready 5.56 setups.

The RDB is KelTec’s downward-ejecting bullpup rifle family, built to give shooters full-length rifle performance in a compact overall package. The downward ejection path and bullpup balance are the major reasons shoppers choose it over a more conventional carbine.

This version pairs 5.56 NATO / .223 Rem, 20" barrel, semi-auto, 20+1 capacity and FDE. Carbine, Survival, and Defender variants each push the RDB in a slightly different direction. Barrel length, weight, sight setup, handguard style, and finish are the details that determine whether a given RDB is better suited for range use, field carry, or compact storage.

Hardware details on this variant include caliber/gauge 5.56 NATO / .223 Rem, barrel length 20", capacity 20+1, finish Blue, overall length 30". For the RDB buyer, bullpup balance and downward ejection are the reason to look here. Barrel length, weight, and handguard/sight setup are the specs that decide whether it fits your rifle role.
