KelTec Quality
The KelTec RDB is a 5.56x45mm bullpup rifle built around a short-stroke gas piston, rotating bolt, and downward ejection path. Placing the action and magazine behind the trigger provides a full-length barrel in a compact overall package and makes ejection largely ambidextrous.

Get StartedWhen determining the value of your KelTec RDB, several factors come into play. Here’s what we consider:
Condition:
Firearms in excellent condition with clean bore, minimal wear, and no significant damage will command higher prices.
Accessories:
Adding accessories, optics, additional magazines and having original packaging can increase value.
Rarity:
Limited edition and vintage KelTec models in pristine condition often have added value.
Market Demand:
Popular models perform well on the market due to their practicality and widespread use.
Original Box & Documentation:
Presence of the original KelTec box or case can increase offer value, lack of the original box will typically decrease the offer value.
Aftermarket Modifications:
Aftermarket modifications and finishing can affect offer values but rarely add significant value in the secondary market.
