Need help finding a QR picatinny-picatinny riser

I found them a few weeks ago while wandering down a rabbit hole, and neglected to bookmark it.

Something like this;

That does not have the offset rail, and is of quality that will hold up [READ - not NcStar or UTG…airsoft].

IIRC the ones I found were a picatinny to picatinny rail, quick release lever, and either 3 or 5 slot. Price was in the $50’s per and of a brand I had not heard of [Again - not NcStar, UTG, airsoft, other el-cheapo crap].

I spent near 2 hours searching for them again last night with no success.

TIA!

Not quite $50, but works well…

You can find it cheaper if you search around…

Thanks cjt50. I found those and another by ARMS after another 4 hours of searching this morning. Killing me that I can’t find the others I was looking at.
