The bottom post has very fine threads. Turning the post counterclockwise will raise the level of the front sight post, effectively lowering the POI (Point Of Impact) on the target. A second, interesting feature of the FR8’s front sight post is that it also has a windage adjustment feature. The post is eccentric on the base. That is, it is not centered on the base, but slightly off set. This way, turning the base very slightly effects a change in windage POI. It starts 0.122 at the bottom and tapers to 0.054 at the top. included new ....front sight post set screw....front sight post...sling ring.............................................................Please Note : I used three triple frames (3) in the picture so you can see the details of all sides...LISTING.. is for ONE triple frame.... one post... one sling ring pin ....one set screw....and one grenade ring bushing....and grenade ring spring...
