Has anyone tried the rails by Premier Shooting Solutions?  http://premiershootingsolutions.com/product/ak-master-mounttm-side-rail/

If anyone has any feedback, I'd welcome it.

Has anyone tried this???

Probably not, looks like a fairly new product. Curious to see how well it'd work.

I don't have one but a friend does and I've handled it in person. It seems like it's a well made product and the RS Regulate mount I was fiddling locked up tight and stayed solid. I haven't done any testing to check return to zero but first impression is good. 

I am likely to help my friend test his out in the coming weeks though

I just installed one on a buddy's AMD65. Very well made. Getting the FCG pins to both fully seat at the same time took multiple attempts. The plate is a very precise fit. One seated the FCG pins fit perfectly in terms of length. There is zero wiggle. Vibra-tite at a Fat Wrench to properly torque the screws. The domed heads of the screws did bump the Armacon safety out a touch when the safety was off. I just dropped in the AK Master Mount safety which my buddy bought just in case.  He had purchased the RS Regulate AK301M/AKML/PA Advanced Micro Dot combo from Atlantic for the rifle. I installed that without issue. The RS mount locked up tight with no wiggle on the rail.

Thanks, any input is appreciated.
