The WLS-1000 System, includes the T-3 flashlight, pressure switch and two mounts to attach the light to rifles and shotguns. The Compact T-3 adjusts from spot to flood and runs on 2 AA batteries (included). Mounts fit firearms from .22 LR to 12 Ga. Pressure Switch End Cap lets you remote operate light. Comes with 10-in. curly cord.
I mounted this system to my .223 AR 15 and it works GREAT. mounts solid to the barrel and lights up a good 50 yards ahead of me and i can now use my scope at night now. my package didnt come with any velcro to mount the pressure switch with but i also got a laser and its velcro wouldnt stick to the gun so i ended up using black electrical tape to hold the switches to to the gun. great buy for the price.
Pros: Fairly universal fit: two sizes of clamps for shotguns & rifles/small gauge shotguns. No other hardware needed and tightens pretty well to stop any motion. Easy to mount in pretty much any direction on any part of any barrel or similar sized tube. Pretty decent pressure switch comes with adhesive Velcro strip for removal.
Cons: As the price would indicate... it's cheap. Low-quality/intensity bulb and questionable weather-resistance (not tested though).
Overall worth it unless you need a really fancy get-up.
