New FAB Defense GL-CORE CP Stock and GCCP Cheek Rest

Several months ago FAB Defense has introduced a new AR-15 buffer tube compatible stock called GL-CORE. Recently they have released an upgraded version of that stock which features a three-position adjustable cheek riser added to the initial design. The new stock is called GL-CORE CP.

The cheek riser is marketed to be especially useful for AK-47 and VZ-58 rifles and their derivatives. It allows adjusting a proper cheek weld height when using these rifles with optics. This stock comes in three color options – black, OD green and FDE.

If you already have a GL-CORE stock but like this newer version more or need it to use with a scope on your AK, you don’t have to get the entire new stock. FAB Defense has also introduced the cheek rest as a separate product. It will fit the GL-CORE stocks thus converting and upgrading them to GL-CORE CP.

The separate cheek rest is called GCCP. It is a user installable part and doesn’t require gunsmithing skills to fit it to the GL-CORE stock. It provides about 1.5″ (40 mm) of cheek weld raise and adds 4.5 oz (128 grams) to the stock weight. The GCCP cheek rest is made of glass reinforced polymer and comes in the same color options as the GL-CORE CP stock.

    Rob Ski at the AK 47-74 Union has been testing this stock (he may also be involved with its design- he hasn’t been clear on that, although I believe it to be the case) and so far it’s lived up to his expectations. For folks in the AK world, Rob is known as one of the most respected and honest guys in that genre. Fwiw.

    Why does everything that FAB Defense makes look so ugly?

      Perhaps you should get a glass of wine and take some time to learn to appreciate the clean lines, minimalist structures, simple functionality expressed thru mathematical calculations, and polygonal structures of a well designed mechanical device.

      I find fault with your aesthetic judgement. Or I am just being contrary to a fault as the SO calls it.

      • iksnilol

        That’s exactly the issue, there is no clean lines (a blur at best) and the structure is far from minimal (if anything, it looks overmolded).

        Probably functional, but looks like somebody scaled up a G.I. Joe toy gun. So I’ll agree with your SO.

    I think a better story would be about that scope mount

  • That angle looks so wrong. The rest is okay.

    It’s FAB Defense, so this will cost about $250. And the cheek riser alone will be $90. That’s my prediction
