The time has come for me to spend some money on an upper and I can't seem to find what I am looking for. I want to keep the complete upper assembly under 400 and want a 1:9 twist with a chrome lined barrel. Any suggestions?
Google the DS arms company, they are one of the current contractors for the Army's M4s. They sell complete uppers in that range, several different options.

PSA, my wife's AR has one of their uppers on it and it'll eat thru steel ammo like it is an AK.
