I have a standard a3 upper, and i would like to mount a Mueller eraticator scope to it. I would like to be able to remove the scope via a swan mount and retain zero.

Here is the link to the scope. Its a 8.5-25x50.


Right now I am thinking a ARMS #63, but i dont know what rings to use with it.

I'm sure someone has been here before probably with the same scope, I have heard nothing but good things about it, plus you can pick it up at eabco.com for $199.

Thanks - Jon

Be sure to consider eye relief as well as height - the Picatinny rail on a flat-top may not let you mount the scope far enough forward for a comfortable position, especially in prone. I use an extended riser (1/2" high) made by Accuracy Speaks (available direct or from Brownell's) combined with standard-height rings. There's now a similar one available from Compass Lake Engineering. This gives me an extra 4" of rail and lets me mount a Leupold 6.5-20x50 LRT (a rather long scope) and gives me the option for an extra 15' of built-in elevation for long range work. I'm using Burris Signature Zee rings - they are inexpensive and work well, even though they don't have the macho look many seem to like. They use a floating plastic bushing to minimize stress on the scope tube and simplify installation, and offset bushings are available. Bushings with a 0.010" offset are included with 30 mm rings, and 0.010", 0.020" and 0.030" bushings can be purchased for 1" rings. They're inexpensive and work very well. I use them on my spacegun to mount a VX-III 6.5-20x50 LRT and have never had a problem with them.

Also remember that your windage range is restricted when you are at maximum or minimum internal elevation. You can't apply maximum elevation and windage simultaneously due to the round scope tube. You won't need large amounts of windage at 100 yards, but you could need 20+ minutes at 1000 on a windy day. There are minor optical distortions that may be more apparent off center, but the biggest reason to stay on center at long range is to have adequate windage adjustment available.

At the very least, consider an ARMS 36 EX to extend the rail out...that's a long scope, and you'll need to move it forward some so your cheeck isn't all the way back on the buttstock. Plus, it'll give you a little more height, which will help with that 50mm objective...you can probably use med or high rings instead of ultra high.

If you can afford it, the LaRue mount IS very nice, and would work great here. Depending on the length of that scope, you might even need the EER instead of the SPR.

Just for grins, I stuck a Weaver Grand Slam 6x20x40 in my EER...it was *perfect* in terms of eye relief/cheek placement. At 15" +, it's a pretty long scope, so the EER helped move it forward...more so than the SPR would have done. Same deal with my Buckmaster...it's as long as the Weaver, but there's more tube behind the adjustments...and it worked very well with the EER too.

The eye relief on both those scopes isn't especially long, it's just that the scope themselves are, so you have to consider that when choosing a mount.

As the scope choice you've made is decidedly on the cheap "junk-optic" side, spending boo-coo bucks on a mount like the ARMS or the LaRue would be a terrible waste of money, IMO.

Buy some cheap high rise mounts and save yourself some money.

Or save your money for a Leupold optic, which is well worth the cost of decent mounts mentioned above.
