Was told about this stuff, and picked up some to test. Since I know someone who's planning to try out their Black Rifle Balm, I ordered the Ma Deuce Juice, since I like grease for frame rails and such. Fast shipping, ordered it on the 6th and it arrived on the 10th. And they threw in a bottle of the Balm.
Here it is:
Holding that plastic pad vertically for more than a minute, the Balm didn't run, it just sagged a little, very slowly; the Juice moved not at all. Put the pad on the angled front of the desk and left it there while typing, after about three minutes the Balm had sagged about 1/8"; unless it thins a lot when heated, it's not going anywhere. The Juice stayed right where it was like a good grease.
Added: it's been sitting at that angle for about ten minutes now, the balm has sagged about 1/4".
From the site, on the MDJ,
...a lightweight grease that provides unmatched longevity, lubricity, wear-resistance, and protection for firearms. Its consistency is about an NLGI #0, which is roughly the consistencly of mayonnaise, only creamy and stringy- excellent for application and staying put in sliding systems.
...robust additive package, etc.
On the Balm,
...lightweight grease appearing somewhat as a gel, engineered with modern rifles in mind, where enclosed constructions, tighter tolerances, high heat, dust, and large volumes of fire in austere contditions are a reality. Just like Ma Deuce Juice, it stays where you put it, even in extreme heat, but BRB is carefully engineered to allow just a small amount of "flow", permitting a little ancillary movement and spread during weapon cycling.
'Gel' is a good description. That's been sitting there as I worked on this, it's sagged that 1/4" and that's it.
Mentioned once before that one of my favorite test beds for lubes is my .22 conversion for the 1911; if the lube doesn't work well, it won't function properly. So I'm going to clean it and the frame to bare metal, lube it up and shoot it; and I'll try both, cleaning thoroughly in between. And I'll decide what other stuff to try it on.
Results to follow, but it'll take a while.
