Good choice. It's what I went with as well with my SL8/5. I found that with the mount I had difficulty getting clearance over the iron sights. I tried mounting the Mark 4 CQ/T but the rear iron sight got in the way. For my eye relief the eyepiece had to be positioned back over the rear iron sight. Plus I like the backup redundency and look of the iron sights so didn't want to remove them.
The scope wouldn't quite clear the rear sight now so I took it apart and fabricated a shim to allow me to lower the ghost ring about a 1/4" past where it would normally bottom out by compressing the set spring. Now the scope would fit if the rings or the rear sight were in a V position; neither up or down. This allowed the scope use but the iron sight would have to be recalibrated if I wanted to use them. Ok as long as you never use the iron sights, which one may. It worked for a bit but started to nag at me. In addition I had to notch more spaces for the scope mount as I'm
still waiting for my short rail from Wolverine (since last October).
So to fix the iron sight utilization issue I ordered an ARMS #12 quick detach mount and this gave me the slight extra clearance I needed plus the quick detach option I prefer allows switching between the telescopic scope, iron sights or a red dot scope if desired.
P&D in Edmonton have some in CQ/T's second hand for $800 used in decent condition. Apparently they came from a security outfit for the Pickering Nuclear power plant. These also have the low light settings for night sights that are not availible for import anymore from the states as far as I know.
I've included a pic on how it looks on mine. I'll look better in my opinion when the notched short rail and pistol grip/folding stock comes in... hopefully next month. It may look long but at 18.5" its legal for gophers to coyotes which is what I wanted. Hope the info helped. Cheers.
