US Optics Sako Quad 20MOA rails discontinued?

[Kiba]

I have DIP scope rails on both my Sako Quads right now and I've never been 100% satisfied with the setscrew mounting system. Besides sitting a little crooked, one of my Quads came with the DIP rail installed by the original owner and whoever installed it got the setscrews a little too snug and the rail started to spread and lift off the dovetail at the front of the receiver.

I was finally going to order a pair of the USO 20MOA Quad rails this week and I can't find them listed anywhere. Several vendors say they're discontinued.

Anyone have a line on a pair of the USO 20MOA rails? I'll probably call USO tomorrow but they don't seem to have picatinny rails for any rifles listed on their webpage anymore.

This is not good news for those of us awaiting these EuroOptic custom Sako Quads equipped with those DIP rails.

I wouldn't say bad news... the one DIP base that is spread and tweaked is because of installation error by the original owner. Those setscrews were way too tight! With GAP handling the assembly of the EuroOptic builds I think they're in good hands.

The rail on my first Sako quad (which I installed) is just fine because I only snugged the setscrews and let the loctite keep them in place. Still, you have to be careful not to overtighten them and snug them up evenly to keep the rail level.

Another option, although semi-permanent, would be to epoxy the rail onto the receiver. Something along the lines of EA9394 would be extremely stable and tough. I'd rather not do that as it would be a real pain to remove if needed. The USO rail requires drilling & tapping 4 holes which is much less permanent provided I can find a pair in stock somewhere.

Another plan I'm considering is drilling & countersinking the DIP rails for 6-48 or 8-40 weaver head torx screws and then drilling & tapping the receiver. This way the rail is held down by the screws rather than the setscrews forcing it up against the dovetail (which can spread the rail if you tighten those setscrews too tightly.)
