12'' Havoc 37Mm Flare Launcher Black

The Spike's Tactical 12" Havoc 37mm Flare Launcher is a breech-loading launcher designed for shooters who need a reliable tool for field signaling, smoke operations, or training scenarios. Built to clamp securely to any Picatinny handguard measuring 7" or longer, this launcher lets you deploy U.S. Coast Guard-approved 5¾" flare, smoke, or gas rounds from an AR-platform rifle. It's purpose-built for operators and trainers who want integrated launcher capability without sacrificing their primary rifle setup.

The Havoc's design prioritizes quick, confident cycling. A pushbutton breech mechanism opens the launcher tube in a single motion, making it fast to eject a spent round and load fresh ammunition. Unlike older lever-lock designs, Spike's Tactical engineered the STZ pushbutton cylindrical breech lock for superior strength and reliability under field conditions. The 12" launcher tube slides forward to accept rounds from the rear, keeping the loading path intuitive and unobstructed.

Construction is purpose-built for durability: a 6061 T6 aluminum tube and grip paired with hardcoat anodize finish, combined with 1018 cold-rolled steel components in oxide-coated black for corrosion resistance. Mounting hardware and instructions are included. At just 2 lb., 14 oz., it adds minimal weight to your setup. The launcher measures 12-5/8" overall with a 5" tube length, fitting seamlessly into modern tactical carbines and training platforms.

If you're looking to build a dedicated launcher-focused rifle platform, Spike's Tactical also offers compatible Kaos Stock Systems that adapt the Havoc into a stand-alone weapon system, pairing it with an M4 stock, pistol grip, Picatinny top rail, and buffer tube for a complete solution.
