Kaos Stock System For 9'' Havoc 37Mm Flare Launcher Black

The Spike's Tactical Kaos Stock System for 9" Havoc 37mm Flare Launcher transforms a rail-mounted breech-loader into a complete, standalone weapon platform. If you're running a Havoc launcher on your rifle's handguard but want the option to deploy it independently—whether for field operations, training exercises, or emergency signaling—this stock system gives you that modularity without swapping hardware. It pairs the launcher tube with a full M4-style stock assembly, so you get a purpose-built setup that's genuinely different from the typical aftermarket approach.

The system centers on Spike's proven 9-inch Havoc launcher, known for its side-pivoting breech design and push-button cylindrical lock (stronger and faster than lever-type mechanisms). That breech swaps spent 5¾-inch U.S. Coast Guard–approved flare, smoke, or gas rounds with a single button push. The Kaos Stock package bundles the launcher with a complete lower receiver assembly: ST M4 stock, mil-spec A2 pistol grip, 1913 Picatinny top rail, buffer tube, latch plate, and castle nut. It's built from 6061-T6 aluminum and 1018 cold-rolled steel with hardcoat anodized and oxide-coated black finishes—solid materials for a tool that might see heavy use.

Weighing just over 2 pounds and measuring 9⅜ inches overall, this isn't a precision rifle platform; it's a specialized launcher system designed for the specific role USCG-approved munitions demand. Most aftermarket AR-15 stocks, latch plates, and grips are compatible if you want to swap components later. If you need a dedicated flare or smoke launcher that stands on its own and accepts standard lower parts, this system cuts out the guesswork.

Frequently Asked Questions

Can I use aftermarket AR-15 parts with the Kaos Stock System?

Yes. The system is compatible with most aftermarket AR-15 stocks, latch plates, and pistol grips, so you have room to swap components if you want to tailor the setup to your preferences.

What munitions does this launcher fire?

The Havoc launcher is designed for 5¾-inch U.S. Coast Guard–approved flare, smoke, and gas rounds. Always follow manufacturer and local regulations when handling and deploying munitions.

What's included in the Kaos Stock System?

The system includes the 9-inch Havoc launcher tube, ST M4 stock, mil-spec A2 pistol grip, 1913 Picatinny top rail, buffer tube, latch plate, and castle nut—everything you need to assemble a standalone launcher platform.

Is this the same as mounting a Havoc launcher to a rifle rail?

No. This is a self-contained system with its own stock and lower assembly. The original Havoc clamps to a 7-inch or longer Picatinny handguard on an existing rifle; the Kaos Stock System is a standalone launcher that doesn't require a host gun.
