PH5E sight and safety catch

[Gil Boyd]

Chubbs,
Found what I was trying to explain.
Pictures tell a thousand words but it is the 5c and you can see the shaped metalwork on the base of the sight as a comparison. I can't find the 5E images I had, but they are squared at the point the safety catch lays forward.
To fit the 5E from memory to a No4 Rifle, and thats what it is a memory, I vaguely remember you have to have the correct adaptor plate and attach it via the two small allen bolts, that will then clear the catch without any mods. I'll keep searching for an image to explain wait out...............
