Sorry for the lame question, but is the 10 FCP-K in .308 (#18608) center feed or staggered? I think it's staggered, but not sure... I'm looking for a stock that allows LOP to be adjusted.

I'm not sure what stock would fit my rifle. I'm looking at this one, http://www.combatstocks.com/Choate_U...rfeed_Only.cfm, but it says centerfeed and not detachable magazine. I'm totally confused...

Once I found a stock I'm thinking of attaching this to make it adjustable: http://www.tacticalworks.com/Choate-...zed-Black.html

I shoot almost exclusively from prone and when I shoot uphill and tilt the weapon upwards, the scope gets closer to my eye and thus the eye relief suffers. I usually end up putting a tshirt or something between the shoulder and the stock to increase LOP, but I would like something more permanent.
