The Fenix ALG-18 fills a real gap if you're running a rifle or shotgun that doesn't have rail attachment points. Instead of settling for a handheld light or getting stuck without one, this mount lets you clamp a quality Fenix flashlight directly to your barrel.
Designed for simplicity, the ALG-18 mounts to any barrel with an 18-23mm diameter using nothing but your hands. There's no need to break out tools or fiddle with complicated hardware. The thumb roller mechanism lets you secure and release it quickly when you need to swap lights or access your barrel. The aluminum clamp is lined with protective rubber pads that grip both your flashlight and your barrel without marring either surface.
The entire mount is built from A6061-T6 aluminum with a Type HAIII hard-anodized finish. This isn't just marketing speak – it means the mount can take the abuse of field use without corroding or getting beat up. The hard-anodized finish resists scratches better than standard aluminum, and the engineering keeps everything square and tight through hundreds of rounds.
The ALG-18 works with Fenix flashlights that have a body diameter of 23.5-28mm and a head width under 70mm. That covers most Fenix tactical lights including the TK16, TK20R, TK22 TAC, TK25R, PD35 V3.0, and PD36R models, among others. One practical note: if you're running high-volume shooting sessions where your barrel gets genuinely hot, remove the rubber cushions before mounting. The rubber can soften under sustained barrel heat, and you want to avoid that on a quality light.
The ALG-18 is compatible with most Fenix tactical flashlights that have a body diameter between 23.5-28mm and a head width under 70mm. This includes models like the TK16 V2.0, TK20R V2.0, TK25R, TK26R, PD35 V3.0, PD36R, and many others. Check your specific light's diameter to confirm compatibility.
No. The ALG-18 uses a patented thumb roller mechanism for quick assembly and disassembly with no tools required. Simply position the mount on your barrel and tighten the roller by hand until it's snug.
The rubber pads built into the clamp are specifically designed to protect both your light and your barrel finish. However, if you're doing high-volume shooting where the barrel gets extremely hot, remove the rubber cushions to avoid any potential softening from the heat.
The ALG-18 fits weapon barrels with a diameter of 18-23mm, which covers most rifle and shotgun barrels. If your barrel is thinner or thicker than this range, this particular mount won't work. Measure your barrel before purchasing to confirm compatibility.
