Looks like my post hit a nerve there - that was not my intention in the least. Products like the one I described above are being assembled by a couple of manufacturers already. I just want a Bushmaster because, after owning Colt and Armalite products, I've satisfied myself that your company makes the best! Should you make an M4 upper with 16" barrel, 1/7" twist with no muzzle break, A2 or A3 receiver, then I will buy one. I fully understand that demand must be great enough to justify the production. I'm just putting it out there, for what it's worth.
