I bought a Troy flip up rear sight to use with my SEBR. I have both in hand, now, and I think I'd rather have a simple, good old fashioned carry handle.
The sight is still new in the box. I took it out to see it, then put it back.
I'm asking $120 (shipped) for it. I don't have a picture at the moment, but if you're interested I can provide one.
Email me if interested.
(SORRY, IT'S SOLD NOW. THANKS FOR LOOKING)
