The Boondock Ballistician goes over the KelTec RDB, a 5.56 bullpup firearm featuring a 17-inch barrel within a 27-inch overall length, comparable to a 10.5-inch AR. While weighing approximately 7 lbs, its rearward weight distribution resulted in a perceived lighter, front-light feel when shouldered. She details its short-stroke gas system, noting AK-like recoil, and demonstrates the rear-located magazine release for quick reloads. Highlighting the ample rail space and fully ambidextrous design, including a downward ejection system minimizing gas blowback, she praises the bullpup's handling and usability.
However, she cautions about the stock handguard's heat and a potentially burning steel pin, recommending an M-LOK replacement and dismissing zero retention concerns with rear-mounted optics. She also advises practicing reloads due to the bullpup layout and acknowledged potential durability issues with the stock and pistol grip.
