I need the help of the collective hive.

I bought a Romanian mini Draco.  I need solid rail mounting options, to mount a red dot.  MI makes a railed forearm, but is it solid enough to hold zero?  Mounting optics on a hand rail is generally a bad idea, but I don't know how solid this rail is either.

There's another company (Texas dog???). That makes a replacement dust cover with a rail.  But that seems like it would move a lot too.

What says the hive?  Any suggestions?

I'd skip the side, topcover, or fore end rails. Check out the Attero arms mount. I believe that Circle 10 AK, Midwest Ind, and a few others make similar if less well thought of mounts that replace the rear sight leaf.
