Geissele Automatics ALG Go-Juice 0000 Very Thin Grease, 4 oz

I've been using this for a few years and it's fantastic, especially for ARs. Put it wherever your BCG shows signs of wear and it will run in any condition. I only use this and eezox to keep my ARs running. I just left an AR in the truck over night in 20 below temps. Went out the next morning, it warmed up to about -14, and it was as smooth as summer time. Charged with the flick of a finger and ran flawlessly. I can't live without it. Side note, I have never used it on a trigger.

It is almost like oil. An oil that lubricates and yet remains where you put it. Seems to be unaffected by high temperature. Allows cleanup with a paper towel. Fouling that once was difficult to remove wipes away. A little goes a long way.

** So I’m really doing this review to generalize it enough to get the message out to the public where people won’t get offended by the end use the product was designed to do. Where my first nag review was short, sweet, & to the point. now it’s long winded & bloated sorry y’all...it was blocked from being shown due to someone getting their feelings hurt over what I said I used it for... how is is that offensive all the sensitivity warriors out there, pffft...sensitivity... Anyway, I’ve had more time to use this lubricant now, and can give it even more objective review it is are the type of lubricant that you must maintain, it’s not something You would use on ball joints because it has an ultra low viscosity but it works really well on metal parts that I rub against each other and you don’t want to use some stinky thick axle grease type compound lubricant that is stinky and stays forever because the nature of it. It is also very difficult to clean up. The 0000 grease is a thicker liquid not gel like. For what it’s designed to be used for, it excels. Because it’s thick enough and also to be thin means ultra lubricity between metal parts and reduces the COF . However, I have noticed on some of the things that I’ve used it on that if I left it sitting on the parts for storage and not pre-use protection, it has a drying effect that occurs and if left on the parts for too long (over winter), that it did show some minor signs of oxidation not really corrosion but But it was concerning. I just use good ole CLP if I am going to leave the parts unused for extended periods. There are a myriad if things this could be used on. Also, it does not take much to be effective and too much can actually cause issues depending on. How and what it’s used on. But it and try it! Stephen P TX

While it’s not the only grease I’d recommend using, it’s a fantastic grease for carry, competition and duty weapons that need lubrication without dripping, migrating or leaking everywhere while in storage or standby mode. Using it quite a lot in my AR platforms, auto pistols but prefer to use a heavier EP grease in high load areas (I.e. locking lugs, cam pins etc). I’ve known Mr. Geissele a long time and if he sells it, you can bet it’s a well engineered, well made and well tested product worthy of trusting with your life.

Love the sliprisity of the GO-Juice. Had a feeding issue, applied a small drop on my slide, no more feed issue. 12/12/2021 Have been using this product exclusively on my firearms, and can honestly say it is by far the best I have used to date. Have read some indicating it is NOT an all purpose firearm lube, most specifically "striker fire" those pistols are just plain annual anyway. That being said ALG also makes the oil version, have both on your bench. With striker fire it makes minimal difference what you use it matters where and how much you apply. A little dab will do ya. You from my exsperience need to shake this rigoursly before use, it does seperate. I use the seperation to my advantage meaning you get a drop of oil rather than the slightly viscous material once shaken. Buy some get both versions this is better than most anything available.

Took off one star because this stuff is marketed almost like a gun oil, or the best of both worlds between oil and grease. It’s not. It’s a grease. A very good, very thin grease, but still a grease and hence not what you want for firearms 99% of the time. The appeal of grease is obvious: it has the “staynacity” that Bill talks about, coating parts without being flung or burned or evaporated or hydrated or agglomerated and clumped off. There are lots of cases where this is what you want, but very very few of them on modern firearms. I find that a drop or two of this grease every few hundred rounds in my AR bolt provides smoother action. However, any amount of it near a i.e. a Glock’s internals quickly results in gummy mechanics. Unless you shoot a lot and know what you’re going to use this for and why, stick with a good corrosion fighting gun oil. It’s great for its purpose but unless you know you do, you probably don’t need this.

None of my firearms see any oils other than Geissele products. Purple drop is great on any trigger. Def has a great viscosity and doesn’t gum up or collect any debris. Will buy again and def recommend

I’ve had the standard go juice for quite some time and needed a grease so this was my go to since I love the juice. Easy to apply and stays in place well. Will have this for years to come just like my go juice now at still well over 3/4 full with five years of ownership. Great product from ALG and Geissle.
