We just received an e-mail from MilSim Labs announcing a new line of glow in the dark tracer ammo for 40mm grenade launchers. MilSim Labs is known for producing all sorts of foam replica weaponry from 40mm projectiles, to knives to shovels and soon you will be able to purchase tracer slugs for your M203s and other launchers to fire at your friends at night. It sounds like these will even glow for long enough to be found and retrieved during night games.
“We are launching a new line of glow in the dark foam products. Coming mid December we will be releasing 40mm foam slugs in glow foam. They are made with a new generation glow formula, not the mix commonly used in tracer BBs and most glow in the dark toys. Charge for 5 min and it will glow for hours instead of minutes!!!!” -Seth C, MilSim Labs
