Overall a good value. - Shield Sights SMSc Compact Shield 1x Mini Reflex Red Dot Sight

Bought this red dot for a Springfield Arms Hellcat as (at the time of this review) this is the only red dot available that co-wittneses with the iron sights. With the correct tools, installation is fairly easy. This red dot comes with everything needed. The battery is inserted in the bottom of the red dot base. To change the battery, the red dot must be completely removed. Unsure about how well it will register back into the same position so as not to require re-zeroing. This red dot is plastic, although seems durable. sight picture is clear, dot itself is somewhat small, however easy to pick up and aim. Zeroing controls are easy to adjust.
