I did not want to hi-jack the other 308 barrel thread so I started this one, Okay. I called DPMS today and spoke with a nice fellow. I asked him a question about thier barrels. Are the barrels on the 24'' stainless 1-10's produced in house or are they from another company and assembled to the uppers and if so could you tell me who. Now keep in mind that when I had Spikes build my M-4 they told me I had x-amount of barrel choices, so I went with a Danile Defence. The gentelman at DPMS said they use a vendor to supply that barrel and he was not allowed to tell me who they come from. SO I came here to pull from the vast knowlede of fellow and senior Hide members if any of you may know to satisfy my curiosity.
