9'' Havoc 37Mm Flare Launcher W/Side Loading Barrel Black

The Spike's Tactical 9" Havoc 37mm flare launcher is a breech-loading signal device built for field operations, training exercises, and emergency signaling. This side-loading launcher clamps securely to any Picatinny rail system 7 inches or longer, letting you fire U.S. Coast Guard–approved 5¾" flare, smoke, or gas rounds from your existing rifle platform. It's engineered for shooters and operators who need reliable, modular signaling capability without requiring a dedicated standalone weapon.

The standout feature is the push-button cylindrical breech lock—a robust STZ design that outperforms the lever-style locks common on similar launchers. Load and unload in seconds: a single button press swings the pivoting tube to the side, making round changes fast and intuitive in the field. The one-piece aluminum tube and grip keep weight minimal while maintaining the rigidity you need for repeated use.

Construction is 6061 T6 aluminum with hardcoat anodize finish, paired with 1018 cold-rolled steel components in oxide-coated black. At 2 pounds 5 ounces and 9-4/16 inches overall length, it balances durability with practical carry weight on a tactical setup. If you want to convert the launcher into a standalone system, Spike's Tactical also offers compatible Kaos Stock Systems that integrate the launcher with an M4 stock, buffer tube, and Picatinny top rail.

The Kaos system includes an M4 stock, Mil-Spec A2 pistol grip, Picatinny top rail, buffer tube, latch plate, and castle nut, and is compatible with most aftermarket AR-15 components.
