Available in .5cc - 10cc the Pneu-Dart Practice RDDs are designed and pre-weighted to mimic an actual Pneu-Dart RDD filled with an injectable liquid. The Practice RDDs all contains a solid cannula / needle which is designed to be used multiple times when delivering your Practice RDD to a practice target.
Pneu-Dart recommends that dial-in your projector using practice RDDs to achieve accurate shot placement and ideal impact speeds prior to using the projector to deliver actual "full" RDDs with injectable liquids.
Poly RDD Bodies (.5cc to 2cc) are color coded Blue for easy identification.
Aluminum RDD Bodies (3cc to 10cc) do not have the laser engraving, and are easily identified by the solid needle.
Flight Stabilizers (Type U): Flight stabilizers aid in the flight of the RDD so that the device does not flutter while in flight. They are also useful in having our RDDs work in other non Pneu-Dart projectors.
