The M781 40mm Chalk Round

the M781 40mm Chalk round was designed to be an area weapon in the 1960’s. Since then, technologies have emerged to allow innovations in the round, allowing the 40mm platform to serve purposes beyond their original intended use. Now, the M781 is developed with a signal dye in the nose cone (referred to as an Ojive/Ogive) to train soldiers to fire the M433 Low Velocity HEDP round. These new M781 rounds release orange dye to provide instant feedback to the trainee.

UDC produces M781 40mm Low Velocity rounds for government and commercial sale for trainers and 40mm enthusiasts alike.
