SRS-2 Sight Kit includes:
6 MOA SRS-2 Reflex Sight
Picatinny Rail Mount
Sight Cover
1.5mm Hex wrench for W/E
Battery Tray Opener
(1) CR2032 Battery
(2) Sight mounting screws
2.5mm Hex wrench for mounting screws
3mm Hex wrench for Picatinny rail

The only thing I don't care for is the cover. The soft plastic covers such as the ones from Dream Plastics for the Burris Fastfire 3 will not fit it.
