Got a xs ghost ring rear and front post on mine. Very nice durable sight but takes a bit of practice to get comfortable with it for more than 50 yds distance as the front post is rather blunt.( have a williams 5d and finer front post on another lever that is more accurate but not as durable and was a pain in the a** to get proper height on the front post)Other problem with it and all iron sights is their lack of low light capability. I will only use this setup for drives and daytime still hunting as you lose almost a 1/2 hour of shooting on both ends with iron sights and are severely limited for at least another 1/2 hour on each end for anything more than 50 yds away. Ain't nothing like a scope for dusk and dawn shooting. Similar problem with red dots but at least the good ones have very dim settings for low light. Hope it helps.
