Product Overview

40mm M781

NOTE:  This particular 40mm ammo does not have the primers installed and therefore they are not regulated by the ATF as a FEL item, in other words anybody 21+ years old can purchase without any paperwork.  Primers are included with purchase.  Expected delivery date is 15-Oct-2021.  Order has been placed and our distributor told us about two months before we receive them, but that is a tentative date.

A practice round—used in grenade launchers such as the M79, M203 and M320 — with a powder-dye filled projectile that marks the point of impact during training.
