      Great stock/adapter combo. Built with precision and extremely durable. Thanks.

      Nice product. Damn close to the OEM version.

      After inspection, I would have countersunk the pistol grip screw hole slightly. It would have made lining up the screw easier without cross threading. Very nice product.
