The best grease/lube I can say is the TW25B. I have tried a bunch, this stuff is tops. Mil-Comm is the company. It does not burn off as quickly as many others and rocks in sandy/dusty conditions.

Militec-1 ain't bad either for colder weather.

 

Man for the 24" barrel they are expensive there. I will wait and save a hundred bucks

 

I have had zero troubles with my S&W MP15T.

Can't wait to make it as "Tacti-Cool" as this one.

 

I think you can get one more light on that thing Does that weapon shoot anything or do you just blind everything within a 1/2 mile??
