Measure the outer diameter where the clamp will be attached. On a tapered barrel, the diameter may vary at different points. At the ALG-18 mounting point, it must be between 18–23 mm. Does the ALG-18 fit the Fenix TK20R V2.0 flashlight? Yes. The TK20R V2.0 is one of the Fenix flashlights compatible with the ALG-18.

An Allen key for the flashlight locking screw is included. When is the Fenix ALG-18 the right choice? The ALG-18 is suitable if you want to attach a flashlight directly to a barrel of a suitable diameter. If the firearm already has a Picatinny rail and you want to use it as the mounting point, choose a flashlight mount compatible with that rail. We recommend Check three measurements before ordering. Measure the barrel's outer diameter at the chosen mounting point, the flashlight body diameter where the ring will sit, and the flashlight head diameter at its widest point. If the barrel tapers, measure precisely where the clamp will sit. If the flashlight body has a clip or an additional ring, take that into account as well. Test the fit of the mount on an unloaded firearm and follow the manufacturer's installation instructions. Check that the clamp sits evenly and that there is sufficient clearance between the flashlight and other parts of the firearm. If you later change the flashlight or firearm, check the measurements again. Even within the same product range, both the flashlight body and the clearance required for mounting may vary. Flashlight mount directly on the barrel The Fenix ALG-18 is suitable if the barrel and flashlight dimensions are within the mount's specified ranges.
