Frequently Asked Questions

What makes the Kel-Tec RDB rifle unique?

The Kel-Tec RDB's standout feature is its downward-ejecting bullpup design. This allows for true ambidextrous operation without needing to swap parts, as spent casings are ejected downwards behind the magazine well.

The Osprey 416 Piston Kit converts a standard direct-impingement AR-15 into a gas-piston operated system. This modification aims to reduce fouling and improve reliability by keeping hot gas and carbon away from the bolt carrier group.

What are common issues with the Kel-Tec RDB?

Potential issues include difficulty clearing double feeds and the risk of blocking the downward ejection port with certain shooting grips. Many reliability complaints are linked to improper adjustment of the gas regulator.

Is the Kel-Tec RDB recommended for new bullpup buyers?

Yes, the Kel-Tec RDB is highly recommended for those entering the bullpup market due to its competitive price point, fully ambidextrous design, and reliable performance when properly maintained and adjusted.
