I purchased this fully traded long barrel m203 a while ago from a guy who had it only for photoshoots. I never got to use it in a game either, I only ever got to fire it once as well while testing it attached to my rifle before covid, the launcher seems to work but the 40mm rounds I have dont and I have no clue how to fix them. But will include them in the bundle, you might have a better idea of how to maintain or fix them, as far as I know, they are 40-round mad bull rounds that can use propane or green gas.
looking for 150 or an offer, Not looking for trade as I am out of the sport and moving away.
