Trying to decide between these two mounts for a primary arms GLX 2x.  

The AK master mount has a full version and a short which I like, but it seems the short version doesn’t have much rail, and I’m afraid the scope sits too far back from what I’ve seen in videos.   But maybe that’s a good spot for it, but having all that rail with the full version or Midwest rail just to mount it in the very back.... I might as well get the Master short version.
 I will only use this scope for this rifle, I’ve never scoped the AK before, or shot it yet, So not sure where it’s supposed to go, but seems that this set up the scopes it’s pretty far back.
So either the short a KeyMaster mount or the Midwest industries mount with a little more rail and still a solid one piece, any suggestions?
I will not get the RS regulate, I do not like the two piece system, and this PSAK103 Is well-made.

It depends on the eye relief of the optic, iirc that particular optic has pretty generous eye relief, but I don't know for sure. If you want to be sure then look at the manual for the optic to see what the recommended eye relief is and then see where that would put it when you shoulder the rifle, that will tell you if you need a full rail or if the rear biased rail would work.

Thanks for the reply.

Thanks for the input
