This silver sight has served me well and is is very good condition as it was always demounted and stored in its bespoke case. It has an upgrade in the DECUT sight pin (8/32) version 1.0 with reduced aperture ring insert and/or hi-vis centre pin. Also has threaded block for 10/32 sight pin. Supplied with hex socket countersunk block fixing machine screws and  the four Allen keys that are secured in the case.
