[Alan de Enfield]

Rather than going for the 'short bolt' mounting (at the rear of the PH5C that goes thru the original rear sight mounting holes) you have gone for the full length bolt.

This can cause problems, unless you have put a lock nut 'inside' the original mounting.

It is VERY easy to overtighten that rear bolt and with very little effort you can get it tight enough to distort the rifle body and trap / pinch the bolt. (Don't ask me how I know !)

So I changed it over to the short-bolt.

I found that going for the 'short bolt' option had no effect on the rifle, no apparent 'spreading under load' of the body, and allowed me to clamp the sight up nice and tight so there was no movement.
