The RDB is a semi-automatic, magazine fed rifle for 5.56NATO/.223REM. The bullpup design provides the operator with a compact well balanced rifle. The modular construction allows a multitude of variations or accessories. The RDB features a revolutionary downwards ejection and fully ambidextrous controls, enabling the rifle to be fired from both the dominant and non-dominant side. Two integral MIL-STD-1913 Picatinny rails, located above the barrel and on the handguard, come standard with the RDB for mounting compatible accessories. The RDB maintains a center of gravity over the grip assembly to facilitate ease of handling and balance.Specifications: Action : Semi-Auto Caliber : 223 Rem,5.56 NATO Barrel Length : 16.10" Capacity : 20+1 Safety : Manual OAL : 26.10" Weight : 5.14 lbs Stock Description : Fixed Bullpup
