I have YET to use DOW55 on my G6r rammer. It's been running on Militia lube since it was new. The bolt gets Techt gun drops oil. I service a team mates Ripper for him since he is incapable of maintaining anything and I use Militia lube on it too. I know the manuals say DOW55, but I haven't needed it on anything other than the 3 way on my cocker!
