The checkering looks crude and uneven. The bolt holes are offset (WRA butt plates are the only ones I have seen with offset holes, but that certainly is not a WRA butt plate). The bulge over the trap door hinge pin does not look like bulge on any SA, HRA, or IHC butt plate that I have seen. The very top of the butt plate where the checkering ends and the edge folds over is not smoothly rounded like a USGI butt plate. You can see a line where it is folded over. Just looks like a cheap copy to me.
