Sort of short rant...
I bought a Carbon 15 (carbon fiber) and the manual/parts list that it comes with shows a different lower and upper. The biggest diffrence on the upper is the manual/parts list shows no provisions for forward assist and no dust cover. Shows a completely different buffer as well and some other small items that I guess were unique to an earlier C15.
I emailed them my serial number and asked for an accurate parts list and they tell me they use the XM-15 parts list. After four or five emails, I get the same answer, "we use the XM-15 manual/parts list." Yeah, that's an aluminum upper and lower. I even called them and the same guy answering their emails must be the same dip shit answering their phone as well. They just can't grasp the concept that I want a part number for my C15 which has forward assist and a dust cover. As a matter of fact, my C15's parts are interchangeable with any AR-15. The earlier C15's weren't, which is indicated in the manual supplied with my C15.
When I called and got the same run-around. I told the guy on the phone, "thank god you're not the one building these rifles!"
There's more details, but instead of sending them another email, I'd rather rant some bull shit here... I guess...
This is my first Bushmaster and I'll never buy another Bushmaster again!!! I'll stick with DPMS!!
