Rifle Scopes Which Spuhr for AIAX and 50mm NF?

[redneckbmxer24]

I need to mount a 50mm NF on a AIAX. I want to stick with the 0MOA model since the AX rail already has 30mm built in. I need enough clearance for the bell, and the bikini cover, which I can trim a little if need be.

I know the 1.18" is going to be too low but I'm thinking the 1.35" should be tall enough. If not they also offer a 1.45". Can anybody with a 50mm NF on an AX or even an AR15 with continuos top rail let me know which they used and how much clearance they have. It would be greatly appreciated so I don't have to wait for both to come in before I can order my mount.

The 1,35" is made espesially for the AX and the height is sufficient for 56mm objectives

I had exactly the same question. Thanks a lot Håkan.

same question but I have a defiance deviant action with 20 moa built in and it is going on an AX stock. I will be running the nightforce ATACR which is 56mm.

What caliber kingsfan?
What distances do you consider as the longest you will shoot?

 

[Scorpion King]

.338 lapua and as far as my ability and equipment will let me.maybe 1500 to 2000 yards

 

[Spuhr]

I would probably use the SP4602 (20moa) or Sp 4902 (30moa) both at 1,5" height.
That will Give you 30-33 mils elevation from 100 yards zero.
Really the 20 Moa mount is enough as 30 mils takes you well past the 2000 meter mark.

If you prefer a lower mount the 0 Moa SP4006 will also take you out to 2000 yards with a 300 load

 

[Scorpion King]

Thanks for the awesome info. Thank you so much. I'll go with the SP4006 since the farthest I'll be able to go is probably 2000 with that glass.

Thanks for the information. When your mount came out I believe I saw some pics of it with an ACI attached, is this available for purchase? I didn't see it on any dealer sights.

I have a 20 MOA NF rail and med. high NF rings an my AICS AX on which I've mounted a3.5-15x56 NXS. Bikini takes a little work on the objective bell but is satisfactory. The whole set-up works really well.

I originally ordered a high 34mm with zero base elevation for my S&B 3-20x50 for my AIAX338 and is was just a touch too low. I sent it back and ordered the extra-high and I still need to turn the lens cap off to the side to make it fit but its as low as I can get it.

 

[Spuhr]

Yes we have a couple of different ACI mounts. So that is certainly availible and Mile High does have it in stock.
Here is our cataloge.

What is extra High?
We have mounts today that is 1,18", 1,35" 1,5" 1,73" and 1,89"

 

[Hairball]

I ordered mine from Midway and the high mount (measured from top of base to bottom of ring) comes in at .495 inches (part # sp-4001) while the extra high comes in at .765 inches (part # sp-4002). This is for the Spuhr ISMS 1-Piece Scope Mount Picatinny-Style Matte

Whoever designed the 1.35" mount specifically for the AX with up to 56mm scopes needs to get out their tape measures because this dog don't hunt. I mocked it up with another scope with 40MM objective until my F1 gets here and there is no way the 50MM is going to clear the rail. The scope thats on it measures 1.95" and has .375" clearance over the rail. My other 50MM nightforce measures 2.32". That gives a .005 clearance.

There is no way in hell any 56MM objective scope will fit on here when a 50MM with a very trim objective won't even clear by a red cunt hair.

It looks like I need to exchange it for a 1.5" and hopefully they'll let me do that since it has technically been mounted now.

SP4602 just received. Perfect for STEINER 5-25x56 and AIAX
I tried with my SB PMII 3-20x50. A couple mm space too much: the 35mm mount should be perfect, but I need 6 mils mount because my AX doesn't have split (0°)
