I just received an SWFA 1-4X24 illuminated mil quad scope kit that came with a cantilevered mount for the RDB I'm picking up tomorrow.
The quality looks very good. The scope and the mount look bomb proof. Probably A bomb proof. Maybe H bomb proof. I've read good reports. This is my first cantilever mount and so far I'm impressed. The SSALT mount is available separately. I used HOT10 for their 10% off summer sale discount code and it worked as late as last week.
I started to get a more expensive quick release lever mount like the one ronmar linked to, but decided that I'd try no backup sights and the most reliable scope and mount I could find. YMMV.
If you want to use rings, I've had very good luck with the quick release rings from Leupold. My 50 BMG disassembled the focus tube inside a pricey gold ring Leupold scope after 16 rounds and it was bouncing off the glass on the inside of the scope, but I replaced the scope with a much less expensive Sightron scope in the aluminum Leupold QR rings and they held zero for over 200 rounds.
I hate buying rings. I'm not exactly math challenged, but some manufacturers specify the distance between the top of the rail and the bottom of the scope tube, and others measure to the center of the scope tube, and it's very difficult to determine the proper height of the rings I need. I often get it right on the third mail ordered rings. Grrrrrr. And of course, the terms high, medium, low, etc. are nowhere close to standard between manufacturers, or even between different lines of rings from the same manufacturer.
I do try to match the rings to the rail. For an aluminum Picatinny rail, I'll try to use aluminum rings. For a heavy scope and a lot of recoil, I'll use the beefy "tactical" rings with six screws per ring. For a steel rail, I try to use steel rings.
I just scoped a Savage 338 Lapua Magnum last night and used the Burris XTR signature rings. I like the Signature rings because they have polymer inserts that don't mar the scope tube. The XTR rings came with several sets of inserts that allowed me to effectively add 20 MOA to the rail for long distance shooting. I think different combinations can add 0-40 MOA.
