As pre title looking for a BSA rear sight to suit a mk1 scorpion pistol.
Its a recent acquisition that had the usual buffer jam and was missing 99% of the rear sight.
Added anew buffer, piston o-ring and a new breech seal is on the way.
Its an average condition looking piece so not looking to spend a fortune if it can be avoided.
Fingers crossed someone has a spare for tuppence plus post 8-)
