    I'm looking to build an 18in coyote .223 and love the cheekweld and flat base of the PRS for bags and/or monopod. Is there anything similar that is lighter?
     
    Not that I know of. Also, you might find that a lighter stock won't balance an 18" barrel well, unless the barrel is a really thin profile. I like the PRS on my 20", and that's only a few ounces from the 18". Just a thought...
     
    I can't think of another AR stock that incorporates both: a) the adjustable cheek riser; AND b) the flat bottom/base of the stock. Any way about it, you sacrifice one feature or another.

    For example, the UBR has no cheek riser, but can be equipped with a picatinny rail section at the small, flat portion of the bottom of the stock for a bag rider or monopod. Similarly, you can get the Magpul CTR stock and equip it with a Larue RISR (non-adjustable, reciprocating cheek riser) as well as a Larue POD (Flat picatinny rail mount section) and sort of get to what you are looking for with less weight. Here are links to the CTR setup that I referenced:

    I don't have the exact figures in terms of weight comparison of the CTR/RISR/POD setup vs. the PRS, but it should come in somewhere around 10-12oz best guess (not a ton, but a 1/2 to 3/4 pound or more can be sizable when you really need to shed weight).

    I don't understand the need for a cheek riser on an AR. There's no drop to the stock. On my first AR, I discovered with low or medium rings, the scope was too low for my cheekweld (with standard, factory, collapsible stock). I eventually went with a Burris PEPR mount for the scope to get it high enough, and forward enough for the gun's geometry. I don't know, maybe it's different if you put a 56mm objective scope on there . . .

    Different face shapes will require different comb heights. For me, a zero rise stock like the standard carbine stocks work fine with standard height optics, but I get a better cheek weld with the comb raised .25" or so.

    ^^ This is more or less the reason for the adjustable comb/cheek riser on the AR platform. ^^

    Simply put, given huge variations in optics mounts/rings, the optics themselves, not to mention huge variations in AR configurations/rails, etc., combined with different body/build types and preferences, the adjustability offered by the PRS (and others) in terms of the adjustable comb/cheek riser is a highly desirable feature.
     
    I have an LMT SOPMOD on my 18" coyote/hog rifle and I love it. It balances well and feels great and everyone that has shot the rifle feels the same. I made a homemade monopod for the SOPMOD the other day so hopefully it will work.
