I have a G&P M203 barrel mount, with an M203 handguard for an m16. Also have two G&P 40mm shells. I’m not sure if the shells leak or not, but the M203 and handguard are in great shape! It came with my m16 but have no need for the M203! I am asking 60 plus shipping for everything. Also one of the grenades only has 2 of the ball bearings in it, but the other one has all 4. I noticed that when I opened up to re-lube the o-rings. But I have some more 4mm ball bearings coming for the one that is missing. So once I get those I can either include them or install them! Buyer pays PayPal fees and shipping!
