I've been playing with locations. Originally had level in front of turret, didn't like that much or maybe didn't give it a chance . Are you recommending right behind the turret?
Exactly my thoughts at 1st. Remember these scopes dont have quite the eye relief of a Leupold.
That stock is looong with the THICK, 1" IIRC, recoil pad I added. It could move forward another 1/2" with the current stock.
More than likely I'm going to end up installing the 20moa 1 piece 1.5" mount I have. That'll move It forward further & means I'll need to replace the stock also to get a higher cheek weld. (Luth or PRS3)
On my AR10 PIC below , you can see it sits back a little further than normal (not near as far though) .
