Fenix ALG-18 Flashlight Barrel Mount for Rifles Without Rail Attachments

Mount a flashlight to virtually any rifle with the Fenix ALG-18 Barrel Mount — a simple, tool-free solution designed for firearms that lack traditional rail attachment points. The ALG-18 securely clamps onto any gun barrel measuring 18–23mm in diameter and is compatible with most Fenix flashlights featuring a body diameter of 23.5–28mm, making it a versatile addition to your tactical or hunting setup.

Installation is quick and straightforward — no extra tools required. The included rubber cushions provide a secure, protected fit under standard conditions. Note: If used on a barrel exposed to high-volume fire, remove the rubber cushions prior to use to prevent heat-related damage from barrel temperature buildup.
