Single Slot Picatinny Rail for Sight Dovetail

This part is great. I had to remove a slight bit of metal from the dove tail and then take out a burr that was in the dove tail slot on my barrel. Once this was done I was able to drive the site in and lock it down as instructed. Installed my red dot bore sighted and now I can hit the target out to 50+ yards consistently. I had purchased a ghost ring rear site hoping that would help but it did not so I moved onto this. I am very pleased.
