I have a DPMS G2 Recon on its way and I would really like to have the barrel(stainless) re-profiled to shave some weight. This will be in addition to changing the HG for a 12" MI rail. I want the rifle as easy to carry(light) as reasonably possible and I would like it to maintain acceptable accuracy if it gets some heat in it too. Nothing crazy, but now and again I could see myself going through a couple mags ringing steel and having fun. My plan: - Send the barrel off to Adco for their medium weight contour under the HG and possibly countour, dimple, or flute forward of the gas block. My concern: - I end up with a barrel that wanders excessively when it gets heated. By excessive I mean opens up more than 2-3 MOA. I do understand that barrels are creatures of their own and there is no magical answer to this question. I would just like a general discussion with people who have been over this ground. If anyone knows: Are stainless barrels stress relieved at some point during manufacture? Does the bead blast finish offer any benefit in that regard?
