This is a drop in conversion for the Nerf Rival Pilot to let it shoot Full or Half Darts.

The threaded inline clip drops into the breach and the muzzle threads on to lock it in place.

The air restrictor will need to be removed from the blaster. 

Conversation back/forth between rival rounds and darts only takes seconds.

The inline clip can hold up to 3 standard Half Darts or 2 Full Length Darts. Give the blaster a quick flick between shots to ensure the next dart is seated at the end of the barrel. Stock spring shoots half darts at about 110-120 fps.
