Holosun hm3x does not fit on TUF-22 picatinny rail

[Wakizash]

I don't know what it could be, sorry. We make the same rails for everything from H+K UMP's to the 10/22 and have NEVER had someone saying their scope / red dot wouldn't fit.

Just talked with Dlask over phone, I will reach Holosun to initiate warranty. Sorry for the confusion.

For anyone with the same problem, I turned to Holosun and they sent me another base, still had the same issue. In desperation I thought maybe some kind of shim would work. I cut a piece of pop can aluminum to fit over the underside of the mount. Popped it on, and rock solid now. If anyone needs I can take a photo of it.
