rail buttons

Search in Chyna , that is where many are made

No need. They have a list of distributors, none of which are in China. Their headquarters are in the Netherlands. And I take it back, Amazon is their distributor here.

I'm a bit concerned that the Amazon division of Goliath Corp. is getting too big. Of course, if you did deep enough, you find that the latter owns everything anyway. ;-)

Mini rail buttons are the sweet spot for me. Micro rail buttons can sometimes bind on the rail.

Ok, I have finalized 2 designs for each - 20mm, 15mm, and 10 mm rails.

These are a set of the 16 of 10 mm mini rail guides.
