Solid construction - Vector Optics Flip-to-Side 30mm Picatinny Ring for RDS/ Magnifiers

I got this for my Primary Arms Gen IV LER magnifyer and I fits really well but when it seems to be slightly offset when lined up with my RDS. Not a huge problem but astetically it could be better. The mount is solid and the spring seems to be robust enough to not allow too much wiggle. Also, I found the tension bar or whatever it's called is a bit wonky when trying to line up on the rail but but all in all not a bad choice and cheaper than some out there.
