The KelTec RDB Hunter in black is a 5.56 NATO bullpup rifle with a full 20-inch barrel and a 10-round magazine (brand part no. RDBCBLK). KelTec pairs its RDB bullpup layout with the barrel length hunters and precision shooters want in a compact package. A downward-ejecting system sends spent cases away from the shooter’s line of sight, and the controls are fully ambidextrous for either shoulder. The center of gravity sits over the grip, which cuts fatigue on long days afield. Integral Picatinny rails and multiple sling attachment points round out the field setup.

Key Specifications
