Good report. Thanks.

I’ve used a lot of the Lucas Heavy Duty Lube. I was working with an agency that bought a ton of it and was running it on ARs, Glocks, ect.


It is thick and it absolutely turns to paste when mixed with carbon. It made ARs sluggish in a day.

It’s not a bad product, but I can get better performance from WD40…and I don’t even like WD40.

Solvent content keeps crud soft and parts moving.

Hmm .... Thanks for that. I may have to experiment and possibly reconsider my use of the product. You are referring to the "Extreme Duty" gun oil, and not the grease—yes?

Or is it the Heavy Duty Oil?

Yes, the oil.

It’s a quality product for certain applications, but it’s thick and intolerant of carbon buildup.

In an AR, it had the consistency of toothpaste after 500 rounds or so.

I believe it's worth bringing up again because it is, after all, winter again. Smile


Since you bumped this thread, Garand Thumb did a pt. 2 to the "freezing rifle" test just last week:

He makes it very clear that the protocol is absurd, but they're doing it nonetheless.

No real surprises aside from a few (Springfield Hellion performing better frozen than it often does unfrozen, apparently).

During alerts we would get "augmentees" (deadbeats from all the other squadrons) to supposedly help us man posts usually left unmanned during normal ops.
They were sloppy about leaving their magazines unattended.
Free ammo for me!

If my AR got super wet or submerged I would wipe it down best I could and spray it through out with CLP. It should continue to bang away Big Grin

Ice, more or less the same. Knock it off, wipe it off and CLP it.

Interesting thought about Lucas. But, I’ll offer a caveat.

The “tooth paste” claims are a bit over the top without a little context. And it folds nicely into my one of cold weather “test”. The 6920 in question was purchased in the mid-1990s and was my first “duty” AR15. I’m talking back in the time when dinosaurs roamed the Earth and the MP5 was king. I took at least a class with EAG and a trip to Midsouth with it. Ten or so years ago, a buddy needed an off duty AR so I loaned it to him. He must have shot it quite a bit, because it was filthy when it came home all these years later. In checking with him, it was lubed with both Lucas red, and blue.

Because it was filthy and needed a detail cleaning, I chose it to set outside. And while sluggish, it still worked as advertised with fresh lube and temps that close to zero. “Tooth paste” and all.

Now in recent times, I’ve attended high round count courses (one this summer that was 2300 rounds in five days) and didn’t clean the gun all week. The rifle was my current S&W that I’m shooting the most. It just got fresh lube each morning. And the sludge wiped off the bolt, bolt carrier, and inside the upper with ease. I only had two malfunctions with the rifle and they were dead primers.

And I get the same results shooting suppressed.

I’m fully against tribalism in product loyalty. When I run out of Lucas, I’ll buy whatever is the cheapest most likely. But, I will concede that if your intention is to treat your AR like farm equipment, Lucas isn’t for you.

I watched that part two video this morning. Very similar outcome to the part one, that inspired the thread: The KAC choked in part one, and the mighty MCX Spear fell short in part two. As previously discussed, these extreme tests are almost meaningless, though they do illustrate my initial thought, stated in the OP. Guns made in such a way that they perform on a high level within a reasonable range of conditions will likely have problems when presented with extreme conditions.
