Yeah parts can be a bitch. In a weak moment I let a bsa express sight go to @
Scout in a swap for adjustable bone button rear sight for my no1 with the charger guide on the bolt head. It had already cost me more than I would've liked for the sliding guide. The rear sights are seem to be going for similar money. We were both happy and Scout will actually make use of it now. I did get it cheap though.
I only wanted to replace the sight as the notch had bee filed into a vee.
Looks naff. I do not forsee it ever getting made back into original configuration
