[ARCHIVED THREAD] - m4 feed ramps from factory?

Posted: 8/24/2004 9:03:27 PM EDT

Is it possible to order an upper with m4 feed ramps from bushmaster if you specifically ask for them, or is that something that they do not do? I just ordered a new upper, and forgot to ask about it.

I believe Colt patented it so only they can do it.

+1 Darkest, but Kurt @ KKF will cut them if you want them that bad.

When I bought my mid-length upper from M-A Parts, it came with M4 ramps cut into it.

I have contacted Rock River and they stated that they do but I also called bushmaster and they stated that they do not have a patent on it so they couldnt who owns that patent
