Screws too small - Magpul AKM AK47/74 Furniture Kit

The rear screw for the stock does not reach the washer it screws into, tried moving stuff around and doing stuff different from the instructions, tried for hours and it does not work. Have to go buy a different screw from the hardware store just to make it secure. The instructions are also wrong, it says to insert the screw washers through the rear but its impossible to insert through the rear, theu enter through the front. Would not recommend, much better furniture for sale that comes with proper hardware and instructions.
