Troy Offset Deployable Front and Rear Sight Flat Dark Earth. Set at a 45-degree angle you can neatly fold these iron sights down on either side of the rifle you set them up on. These sights are only designed to work on same-plane rail systems so they won't work with a railed gas block that is offset from the receiver.
