37mm to 12ga Flare Adapter

EXPAND THE MISSION. ONE LAUNCHER. MORE CAPABILITY.

Your 37mm launcher already has a job. This adapter simply adds another tool to the mission kit.

This precision-machined 37mm-to-12 Gauge Adapter allows compatible 37mm launchers to safely use compatible 12-gauge flares, signaling rounds, and blank cartridges. Whether you're heading offshore, assembling an emergency signaling kit, training, or simply expanding the capabilities of your launcher, this adapter is ready to report for duty.

⚠️ KNOW YOUR LOADOUT — 2.25" MEANS 2.25"

Each adapter is precision-machined from durable aluminum and intentionally bored to a depth of 2.25 inches.

That chamber depth is there for a reason: it prevents the loading of a full-sized shotgun shell while allowing the 12-gauge signaling rounds, flares, and blank cartridges we sell to seat properly.

TACTICAL READBACK: Signaling rounds, flares, and blanks? GOOD TO GO. Full-sized shotgun shells? NEGATIVE. NOT COMPATIBLE.
