OK El Cazador, you wanted some pics, here they are.
This started life in 2007 as my play rifle. Once my daughter got old enough to move up from her 22 it kind of became hers. She has shot several deer with it, and lots of varmints. I kept trying to maintain dual possession it, but that really isn't working out. When the scope has eye relief set for me it doesn't work for her, and vice-versa.
I am starting to get her thinking about beginning long range shooting (she shoots real well out to 200 now. She is 9 years old). However, none of my LR rifles fit her. I decided it was time to set this rifle up specifically for her, hence the little rebuild it has gone through the last couple weeks. The fixed 6x SWFA has a good MIL reticle and will dial reliably. The plan is to shoot the 53 VMAX and let her shoot it as far as she feels like.
The rifle is CZ 527 American in 223, with both 3 and 5 round mags. Barrel has been chopped to 18" and threaded, it has an ASR muzzle brake and is shooting through a Specwar 556 K. The stock has been chopped and a heavily modified adjustable buttplate from David Tubb installed. When I did that I had to refinish the stock. I didn't like the round nose on the forend so I slash cut it at the same time to make it a little different.
I ended up with the Warne medium rings. I really like them and the way they fit. RePete's mounting advice was spot on, worked like a dream. Good thing I removed the bolt before I mounted it though. It didn't lack a whole bunch, but the bolt would not clear the ocular. Yesterday I put the bolt on the belt sander and shaved it down. Got it clearing good then smoothed it up nice and sprayed it in Graphite Black cerakote last night. Turned out pretty good for a trainer rifle I think.
