SFAR 16"
Will be mounting a Leupold 50mm objective with 30mm tube.
What cantilever style mount would you use and why?
Thanks

I like the Reptilia AUS.

While I haven’t used one I’ve had one in my possession briefly. Definitely a quality mount. I’m currently waiting on the 34mm rof-sar to come in stock.

I’d also look at and research the Primary arms mounts as they are good price and made in the USA. No idea if they are good or not.

If no budget then just buy a spuhr.

Aero Precision Ultralight. Just over 3oz and a solid mount.

Probably Badger, Nightforce or Sig Alpha 3. I generally like a 1.5" centerline as I've been using that height for years.

The scope probably has the usual 4" eye relief, so ADM Recon-X. If it's a 34mm tube, then maybe Nightforce Unimount of similar cantilever.

There are a couple of ways you can approach this.  A one piece mount such as a Larue, shown with a Leupold Leupold 8.5-25 x 50mm below . . .




Or you can use a riser with rings.  Shown with a Leupold 4.5 - 14 x 50mm below . . .

I've been pleased with mine. Might take a minute or two more to level if you don't want to do hex wrench trick, but it's far from complicated.

Otherwise, it's going to be hard to beat a utg accusync cantilever mount. 2 ounces heavier but traditional horizontal rings and two seperate dedicated recoil lugs plus they're see through for half the price of the aero. Edited to add: you'll want the high profile for a ~1.5" centerline height, and 34mm offset or 50mm offset will be dictated by how much eye relief your scope has.

I like the Seekins mxm, 1.45 height. The lower height makes prone more comfortable. The Nightforce 1.375 worked fine for me as well in the past (42mm obj, but it should clear 50mm.)

How would a dumb coon ass determine what offset? Eye relief of scope below
Eye Relief Low Mag (in) 4.4
Eye Relief High Mag (in) 3.6

I use a condition one from badger at 1.54" but my scope is only 42mm objective. Website says 3.3" of eye relief.

If you shoot NTCH you will need an extra long extended mount. If you shoot with your head back a bit you probably be fine with the standard extension.

If you have a volunteer, pick the shooting position in which your eye is most forward (typically unsupported prone or sitting), and have them measure 4-4.5" forward from your eye and mark the receiver.

Mock up the scope ocular in that location and measure from front of receiver to front of turret bulge. Confirm how the mount manufacturer measures offset.

ETA: I've yet to see relief shrink at high mag. With most scopes, if it changes it gets longer.

Thanks for all the info! First time doing everything myself. I am not NTCH.
Last question, quick release mount yay or nay?
As of now, I don't see the need to swap optics. But I could in the future.

Mostly depends on what the rifle is used for.
Fun gun? It won't matter all that much.
Serious gun and backup is traditional folding sights? Yea, QD.
Serious gun and back up is a mini red dot or offset irons? No QD needed as backups already accessible.

Quick Release - No, just one more thing to go wrong.  If you're concerned about your main optic goes to $h-t and while engaging a raging battle against the zombies, then stick on a side mounted RDS.
