Perfect shotgun laser sight - SightMark Core HX 2.0 Laser Sight

I mounted this on a rail under the shotgun fore-grip just ahead of a pistol grip. The on/off button is perfectly positioned just ahead of my index finger. This laser is a vast improvement in daylight visibility. Now I can shoot my tactical shotgun from any position without having to locate the iron sights.
Pros: Tough, easy to cut on and off, bright in daylight, large battery reserve
Cons: bigger than I thought
