I'm posting a short list of sight systems available for the Remington 870 from Underground Skunkworks. These systems were designed and developed in coordination with my sister company, Grizzly Custom. They aren't currently listed on the Skunkworks website, but you can see them at www.grizzlycustom.com.
Plain Black
Fiber Optic
Gold Line
Tritium
Long Rail
Long Rail with LPA Sight
Medium Rail with Modified LPA and Custom Sight Block
Forward Mounted Rear Sight with Short Rail
I offer a few more front sight configurations than what I've pictured, and if you're interested in something not pictured, feel free to contact me.
