I am about to pull the trigger on a DTA SRS A1 soon and was thinking about having a barrel set up for the 6mmbr. I cant seem to find where anyone has chambered one in the DTA yet. I know it can be a PITA to get this caliber to cycle threw most repeaters easy. Also with the DTA mags are designed a bit different than most and this may also be a source for headaches. So has anyone traveled this road yet?
