Breech-loading 37mm flare launcher clamps securely to the bottom rail of any 7"" or longer Picatinny handguard. Lets you use 5¾"" U.S. Coast Guard approved flare, smoke, or gas rounds for field operations or training. A single push of the button quickly opens the launcher to remove a spent round and insert a fresh cartridge. STZ pushbutton cylindrical breech lock is far stronger than lever locks typically used on this type of launcher. 12" Launcher tube slides forward for rear feed. Mounting hardware and instructions included.

It is compatible with most aftermarket AR-15 stocks, latch plates & pistol grips. Kaos Stock System features a ST M4 Stock as well as Mil-Spec A2 pistol grip, 1913 Picatinny Top Rail, Buffer Tube, Latch Plate, and Castle Nut.
