M-203 beehive with .22lr piney mountain tracers

LMT M-203 40mm Grenade launcher with a sub cal adapter to fire 20 22LR bullets out of it at once, i tried out some of the Piney Mountain tracers a few months ago. the green worked the best but since they are not from a rifled barrel it takes some time for them to light up. this is what Sons of Guns biased their design off of.
