Rear Iron Sight for Adventure Force (Dart Zone) Liberator nerf Blaster
Sandwiches into the stock rear sight, no need to glue.
Intended to work with the existing flip-up front sight.
See photo for Sight Picture
similar to a real-steel buckhorn sight
Note: shell interface fit was based on my own blaster; which is Painted.
If the fit is too loose for an unpainted blaster a quick fix is to add a bit of electrical tape to the underside of the base where it gets clamped into the shell.
