Luke C ( @BallisticAviation) is back at GunCon 2024, this time at the LMT Defense booth to talk to Joe about a not-so-well-known fact: you can legally buy an M203 Grenade Launcher. The LMT M203 40mm “Shorty 40″ rail mounted receiver is designed to be used on any Picatinny rail or as a standalone weapon system in tandem with an LMT stock. Completely civilian legal, the M203 40mm is a barrel of fun with hand-loaded rounds, which are also civilian legal.
