I placed an order for some parts last month to finish all my AR15 projects. It appears the Bushy made a slight error on my order list when I received my order. Couple e-mails to their customer service to find out what was the problem with the order. They had an error on the shipping info for parts quantiy on my orginial order. So, they offered to have the shipping charges waved and send the reminding part of the order. That's was only three days ago since I last contacted them. A big thanks for getting the need parts out to me!
