I found this to be an EXTREMELY informative thread and thought this would help out a lot of people here.
Over 30 different products were tested. It seems like the best results were from Eezox with Tri Flo, PL10, Corrosion X and Weapon Shield CLP coming in right behind. Now some of these are not lubricants, just made for rust prevention. It’s amazing though how downright horrible some of the popular products faired in the testing.
Go to the thread linked above to read more about how he ran the experiment. But to summarize he sprayed the samples with a water/salt mix (to simulate a worse-case scenario) and even left the samples in the rain a few times...
Here is the final picture after about a week. There are several close-up pics in the thread on m4carbine.net.
Depends on your location. I don’t mind meeting half way within reason. The light alone goes for around $250 used. And the pressure pad and tail cap around $120-140 from what I’ve just seen. If I’m off someone chime in please. I’d throw in the mount for free for a package deal at $365.
I also have Surefire M640DFT, M340C, and X300U and Streamlight TLR-7A Flex I’m considering parting with but I have to sell a few guns before I get rid of their jewelry.
I have no problem shipping.
