I have a couple of stocks with adjustable LOP and Cheek Riser and I have to say they are really nice for when you come to bear off hand. As for the mentions of the vertical grip, I have come to find that is also a real plus when shooting off hand. It really helps to position your rear arm in a way that increases your comfort as well as accuracy. If you have ever shot one of the Pro Hunter Thompson Center models you would find this out for yourself. Of course this is only my opinion on the matter and others may find it different for their shooting styles. But I myself find that I shoot my AR's off hand a good bit better that my straight stocked rifles. If you could find one with the same adjustments and in a vertical grip that will fit whatever you are wanting to drop in it, I believe you just may find it may end up one of your favorite rifles to shoot off hand.
