Looking for a good alternative to the ARMS 22 rings for a MK12 Mod 0.  No need for full on replica just something decent. Something that is QD is preferred.  I was looking at the ADM Recon mounts as well.

I'm not well versed on scope heights needed with this type of upper.

The scope with be a Vortex Optics Viper PST Gen II 3-15x44 First Focal Plane Riflescope - EBR-7C Reticle (MOA).

I’m liking the griffin option.  You need to do some homework on the height, probably the taller one.

I have five Mk12 M 0 builds and two Mod H builds, all have the American Defense QD mounts. Those mounts give me a perfect cheek weld with the standard A2 stock and the MagPul STR stock. More affordable than the LaRue version.

Rock solid, zero issues holding a zero. I also use the same mount on my other Aero M5 hunting rifle builds.

Get the Vortex-branded version of the ADM mount. It has the horizontal split rings like the ADM Deltas.

I like Warne MSRs or ADM Delta mounts.

I have an ADM recon mount on my DMR style AR and I like it.

ADM shows the center bore to be 1.5 inches.  The ARMS 22 mount is 1.1 inches according to my Google-Fu.

Warne if you dont plan on taking it off.  They are bullet proof and can be found for reasonable prices.

Aero if you want something lightweight that isnt trash.  However, buying direct from Aero is a shitshow right now.

ADM if you want something removable.  The return to zero is pretty damn good on them.

I went with the ADM delta.  Should be here today with the Vortex.  

One step closer to finishing the rifle.  AEM5/OCM5 is the last step.

Thanks for the help.

Oh and getting the lower cerakoted in FDE and installing the SSA-E trigger and gas buster.

Good choice. The Delta mount is seriously solid.
