The tushmaster I bought in late 06 has M4 ramped receiver and carbine barrel extension. No one seemed to believe it back then, and I didn't see one again until late last year, now alot of the ones I have seen locally have them. I kinda doubt it anything more than using leftover parts from specialized runs.

that didn't last long. anyone get one?

I have two BM uppers, with the M4 ramps.
Both uppers have the M4 feedramps in the barrel extension and receiver. Purchased the first in Nov-08 and the second in Feb-09.

It was the lightweight. I see they are selling on GB for 750ish and they were 500.

If you open and lock the bolt to the rear and look in the ejection port you can see the barrel extension, which the bolt locks into. On the lower edge of it there are 2 shallow grooves that are feed ramps, all ar15s have these. However there is a carbine model of the receiver extension where the angle of the grooves are steeper and require corresponding ramps to be milled into the upper receiver, this is then know as M4 feed ramps.
