Through An Ingenious And Simple Arrangement We Have Solved The Main Disadvantage Of Bullpup Rifles; Case Ejection. Traditional Side Ejection Is Not Ambidextrous And Forward Eject Like In The Fn 2000 Or The Kel-tec Rfb Is Quite Complex.
The Rdb (rifle Downward-eject Bullpup) Features A Rotary Bolt With A Spring Loaded Ejector And An Extractor Facing Down. The Spent Case Is Pulled Backwards Along The Top Of The Magazine And Then Ejected Through A Vertical Chute. The Hammer Is U-shaped And Runs Outside The Chute And Above The Magazine. Obviously The Bolt Travel Is Longer Than Traditional Designs But Well Within The Ergonomic Constraints Of A Rifle. Other Advantages Are Gravity Assisted Ejection Higher Bolt Energy At Feeding And A Slower Full Auto Rate (when Applicable).
The Rdb Is Built Around A Common Steel Skeleton Formed By The Receiver And Barrel Sub-assemblies. Bolt Bolt Carrier Firing Mechanism Ejector Chute And Bolt Stop Are Identical For All Variations. The Short Stroke Gas Operated Piston Is Fully Adjustable For Different Ammunitions And Muzzle Attachments.
