I have a RAMI BD, after shooting it yesterday I too noticed my rear night sight is loose, tiny play from side to side. There is a tiny hole towards the front of the sight, however it is so small I cannot see a screw. I was thinking it could be a retaining pin however the sight is windage adjustable, so I was again erring to a screw. I looked at the exploded view in the manual and they do refer to a sight screw, however I do not think it is in reference directly to the night sight but more generic. I went to my range and looked at their RAMI B with the adjustable sites and it looks like there is also a small hole at the front of the sight retaining the sight assembly, however there is also a larger screw for height adjustment towards the rear side of the sight.
Can anyone source from experience, or looking at their RAMI, clarify if the hole towards the front of their rear sight has a tiny screw that fits into it or clarify if that is a push pin? I am thinking (hoping) possibly a screw, if there is one, that popped out. This would keep me from having to disassemble the slide to get at the pin.
