I picked up a scope mount bar for my E-11 build from Field Marshall. It didn't come with a screw to attach it to the eyesight. I was curious if anyone knows which one to use as I don't think they offer a screw for it I guess? Thanks!
There’s a video on YouTube where they put together the full kit. It’s been a while since I watched it but I think I remember him mentioning the screw sizes as he built it. Worth a look…
