I'm in search of the Mk 8 SMR from Geissele to use on an upcoming build. Unfortunately, because this rail is so good, I'm having some trouble tracking one down. Certainly there's no chance at all of finding one on the Geissele website, so if you guys run across one I'd really appreciate the heads-up. Ultimately I may end up utilizing another M Lok rail but I really like the look and simplicity of this one.

Thanks

I just got mine from Brownells. It's in stock. I'm actually having to return mine because it doesn't fit my upper receiver.

Is the rail out of spec or something like that?

No, nothing like that. I have the Gibbz G4 upper receiver and it's a tad thicker where the set screws on the rail sit. So it's just not compatible with my specific receiver.
