All bad experience - XS Sight Systems Shotrail, Ghost Ring & Standard Dot Tritium Shotgun Sights, Mossberg

$180 is already a hefty price for the product, but it wasn’t all bad since there was a free 2 day shipping coupon code. Later on I saw I was charged $240 instead of the $180 so I looked back and saw they DIDN’T apply my code for the free 2 day shipping after all. I was whatever about it since I’d get it fast anyways but no, I get it a whole WEEK later. And when I open the package, the bottle the product was contained in was BROKEN. I look up tutorial videos on how to install the rail and front sight since I couldn’t figure out why the last screw to the rear sight wouldn’t screw in and each tutorial video showed me I needed an extra long screw that I DIDNT get in the package???
