There are plenty of ways you can add a weapon light to a Ruger 10/22 and plenty of reasons you might consider doing so. In my case, I wanted to be able to illuminate critters who might be getting into the garden or hen house.
I posted a picture on Instagram yesterday of one of my 10/22s with a Streamlight TLR-1 attached in such a way that it could easily be activated with the index finger of the support hand. Someone asked which mount I was using and at the time I couldn’t remember so I checked around online to find out. The mount in question is the Pro Mag Tactical Barrel Band.
There aren’t many Pro Mag products I can recommend but the Tactical Barrel Band has worked out for me very well for more than 5 years. It easily replaces the OEM barrel band found on many 10/22 variants and provides a side rail, bottom rail, and fixed sling loop. You can flip it so that the rail and sling loop are on either side and it is machined from aluminum.
I have come to like this mount quite a bit. It’s easy to install, provides a useful front sling mount, and places the light in such a way that it is easy to active both momentary and constant modes. I would prefer that the side rail was a bit longer but the adjustable clamp style mount found on the TLR-1 attaches securely.
