Drone Round showed us their new 6.8×51 round for use with Next Generation Weapons System.
Here, you can see it next to the 5.56mm NATO version. The counter drone ammunition will be offered in both K & L variants which feature different dispersal radii.
Offering an effective counter-FPV drone solution which can be employed using existing small arms, Drone Round has begun to see limited procurement by the Army, Marine Corps and SOF here in the US as well as by multiple partner nations worldwide.
