I personally cannot afford to have a bunch of tactical lights, one for each weapon and 1-2 for handheld use. I figured I'd get a decent mount like the
Vltor QD Offset Scout Mount so I can quickly & easily remove the light, swap it from weapon to weapon or use it hand-held. One tip about QD mounts, or light mounts specifically, if anyone plans on swapping it from one weapon to another ... don't get a LaRue mount. You need a tool to adjust the tension from one rail to another. The ADM mount that Vltor uses does not require tools. That mount also releases the light from the mount entirely once the lever is released. That's another handy feature, you don't have to carry the mount around if you want to use it hand-held. LaRue mounts do not have that feature. I wish Bobro made a light mount.
I have been seriously considering the
Nordic Components Shotgun Barrel Clamp w/Rail $47.95. Might be able to find it cheaper elsewhere.
Many believe in having a dedicated light for each weapon. I agree, but I'm a huge fan of quality & well thought out QD mounts.
