Anybody shortcut me to a source for these? I’ve googled  for a bit and found some L marked but not the actual 50 M. Going on an AR9 A1 carry handle upper but has the standard A1 aperture in it now.

I used to buy the 9mm rear sight apertures from J&T Distributing. I just checked their website and didn’t see any. I suggest you try calling them and see if they can help you find one.

I dont mean to hijack, but whats the difference between a 9mm aperature and a regular A1 or A2?

Went through my old orders and found the part number for the 9mm aperture. Looks like they still carry them after all.

You're welcome. The panic has made finding the hard to find parts even more difficult.

That’s true and thanks again I ordered from them yesterday.
