The Fenix ALG-18 Barrel Mount, is a great solution for mounting a flashlight to a rifle that does not have rail attachment points. With no extra tools necessary, attach the mount to any gun barrel that is 18-23mm in diameter for a secure fit. For use with most of Fenix flashlights that have a body diameter of 23.5-28mm.

Note: If the Fenix ALG-18 Barrel Mount is used on a barrel with high volume rounds, the heat of the barrel will require you to remove the rubber cushions before using to avoid the rubber from melting.

Olivia K. ★★★★★ Aug 17, 2026

Took it out to the range with a rifle that had zero mounting points, and having no tools needed to get it on was a lifesaver. The clamp holds steady through a full mag dump without slipping, which is exactly what I needed.

Matthew L. ★★★★★ Aug 13, 2026

Fits snug as a drum on a barrel with no rail, and the no-tools design means I can swap it between rifles in seconds. Solid lockup, no wobble even after a few dozen rounds downrange. Exactly what my old shotgun needed for a light.

Slapped this on my rifle without any tools in about 30 seconds, and it hasn't budged through a full box of shells. Perfect fix for a barrel with zero rail space, and the grip feels rock-solid.
