I would go with the Mad Macs Precision but would need to drill and tap the gun which I want  to avoid.  I like EGW but I don't have sight pusher and sometimes it can be a pain pounding into that Ruger dovetail.  That leaves the Burris mount.  Anyone have any experience with these?

I just bought a farrow.tech mount to adapt it to a Nikon Spur for my MkII.  You might check him out.  Two weeks ago he only had about 4 fitments, and checking just now he has one for the Spur.  Just my luck.

I have the burris mount with the fastfireiii on a ruger mk1.
The original sight was really hard to knock out and I would try some heat if I were to do it again.  I put it in the big vice with leather pads and drove it out cold with a steel punch, I can remember doing it because it was a chore and rubber vise jaws and a nylon punch didn’t do anything.
I can’t remember if I had to file the dovetail on the mount to fit, but it was a push fit and then it has a set screw to tighten it up.
The burris fastfire and mount have been solid for about three or four years with no adjustments since the original sight in and I use and carry it it a lot.  It has become my go to gun and it’s all because of the red dot.

I used one of the StormWerkz mounts just to avoid having to deal with removing the rear sight.

don't have a MKii, if it is a standard dove tail (like a Glock) I used a DPPtitanium mount to attach a Vortex Venom to an Advantage Arms conversion unit
