Is this a Keymod slot?

QD mount fit?

Yes, and no. It does fit, but doesn’t lock into place.

This definitely is not a Keymod

I have the same rail on my first BCM lightweight upper. I never thought about that until now. I hope you find out so you can enlighten me. It came with a couple pic rail sections and a qd sling mount. But I’ve never been able to find any other accessories that fit. Which is fine because I actually don’t stick a whole lot of shit on my rifle anyway. Just a farm gun.

"Maybe"something like this ARCA rail ? I realize this is a long shoot... but , maybe it will help someone's memory.

Still no response fro MI. I will post in the subforum.

Maybe just a hole to drop the large portion of a cutter through to lighten the rail inside the length of the slot or to cut something on the opposite inside.
