Delayed shipping, defective screw, no spares in the box - Midwest Industries Rifle Chassis Compatible with Ruger PC Carbine

Item shipped DHL for some reason which increased the shipping time at least 2-3 extra days. When it arrived it arrived with a defective socket head installation screw. Now I have to wait even longer for either Optics Planet to reach out to Midwest Industries to get a replacement part or send the whole thing back for a replacement. I tried to find a replacement on my own but these screws appear to be in standard instead of metric and are not that common the local home depot. If we run the chance of getting defective small parts then Midwest Industries really should supply spares in the box.
