[Big 3 East] Geissele’s New Spring and Go Juice

Down at the Big 3 East Media event, Geissele showed us their new Purple Go Juice. The Go Juice is purple since it will be under the ALG Defense brand. The Go Juice is a bio synthetic lubricant made from GMO seeds specially made to produce this oil. The reasoning behind making their own lubricant was due to Bill Geissele and his immaculate M1 Garand. He had used a vegetable based lubricant and after 6 months sitting in his safe, the lubricant failed to work on the M1. Joe of Geissele said that while petroleum based lubricants are very stable for long term storage, they do not work as well as vegetable based lubricants. So Bill looked into making a stable vegetable based lubricant. It took 7 months to find the right lab that could manufacture the GMO seed used to produce the oil. They have not performed serious heat tests but performs well at 0-20 deg F. No Arctic sub zero temps nor high heat temp tests done. Joe said that flashpoint temperature tests are misleading since the weapon will not get that hot. Go Juice will be available in about 8-10 weeks. They will be sold in 4 oz bottles for $11.50. Well under the pricing for other vegetable based lubricants in similar sizes. Joe said this oil works very well on moving parts. I asked if that applies to pistol slides. He said he recommends a grease since the grease will stay where it is applied. The Go Juice is very viscous and has 200% more lubricity compared to petroleum based lubricants.


Go Juice is purple when you hold it up to the light.



The newest item from Geissele is their braided wire recoil buffer spring. The recoil impulse is more linear and eliminates the common twang one hears in a conventional recoil buffer assembly. The buffer spring is proprietary to Geissele’s buffer. It will be available with an H1 buffer and will be available in a couple of weeks.

Their Super Precision scope mounts were here again. They are made from a 5.5lb solid block of aluminum. The caps are made at the same time as the mount. In fact the caps are cut off using a jeweler’s saw. The caps are serialized. You can see in the photo below one ends in B and the other ends in A.  There are a wide assortment and some are even made specifically for certain scopes. I know they make one for the Vortex HD Razor II. Geissele also makes an SR25 version. The SR25 version is longer and has three clamps. They are looking into a quick detach method that will have the same clamping force as the screw mount has now. They will not compromise for the sake of QD.



Geissele has a Supre Precision mount for the Trijicon MRO. They make it as absolute and lower 1/3 co-witness. They are available for $99.

Geissele’s super charging handle is still undergoing some changes. The black version will be the final design. You can see the texture of the ambi latches are different between the DVC and Black handles. The handle will be $89 and they are going to make an AR10 version.IMG_0997

    Inb4 fireclean comparison.

      I spoke to them about this product at SHOT – it was designed as an alternative to their previous oil of choice and makes a point of avoiding ANY of the household oils involved in the ongoing controversy. They absolutely positively refused to mention ANY company names (which was probably wise, given recent events), but I know for a fact they used FireClean in their in-house guns before the whole mess hit the fan.

      I used a couple of the samples in my guns, and so far, I’m very happy with them. They are VERY similar to FireClean, which aside from a potential lack of corrosion prevention, I was very happy with, as well!

      • Adam D.

        Thanks for the input, Stephen, interesting information!
        If you don’t mind, what do you mean by “aside from a potential lack of corrosion prevention, I was very happy with”?
        Isn’t the Go-Juice supposed to lubricate AND protect?

        • randomswede

          I’m just guessing here, but is it the subtle difference of protect and prevent?
          A thin film of oil will keep air out protecting against oxidation, and this is where my chemistry fails me BUT I understand there are substances that react to rust halting the spread as rust leads to rust and I’d be inclined to call that “prevention”.

          Again, just guessing.

        • Stephen Hubert

          Sorry for the late reply – my main complaint with FireCLEAN was two-fold.

          1. I asked the company some basic questions initially and received prompt answers. When I asked the company directly about corrosion prevention (multiple times) they stopped responding.

          2. One of the comments made by the conductor of the controversial ‘study’ of FireCLEAN specifically commented that if the oil were indeed made up of household vegetable-based oils, it would have little to no corrosion prevention properties (in comparison to other products marketed to the same purpose).

          I was directing the “potential lack of corrosion prevention” toward FireCLEAN – I liked their product, but that was the only part I was skeptical about. I realize I worded it a little strange – re-read it with these comments in mind, and it should make sense.

          • Adam D.

            Oh, I see, thank you!

  • Joe

    I’m pretty sure the 3-clamp mount is actually the large caliber/”Big Bertha” model, not the SR-25 model. I believe the SR-25/AR-10 model utilizes more rail space, but does not include an third lug.

  • GhostTrain81

    Interesting… made from GMO, but is it Gluten Free? My AR has severe Celiac disease.

  • Suppressed

    I like Geissele and the stuff they make. However, I don’t understand what they (and a few others recently) are doing by making charging handles that don’t seem to differentiate themselves from the proven Raptor, and then pricing them the same or slightly more.

    I know it’s good to have choice and competition between manufacturers, but it doesn’t seem like the best expenditure of resources. Of course it’s possible that I could also be ignorant of other motivating factors for these other companies.

  • mk18

    I hope there’s enough space between the rings to fit the USO T-PAL saddle. It’s been a PITA finding a *CANTILEVER* mount that can support the T-PAL. So far, only the Bobro fits. Anyone know the actual measurement between the rings?

  • Bill

    Stop the madness. If it’s GMO, maybe the lube will develop into a sentient being capable of some form of self-actualization, and start firing the gun itself.

    Is it wrong to regret having replaced my EOTech with an Aimpoint, when I could have had a MRO in this badass mount?

    • Patrick Karmel Shamsuddoha


      • Stephen Hubert

        I saw all the mounts at SHOT as well – very nice products, and the pricing is fair from the dealer pricing list I received.

        They were really pushing the return-to-zero and no-torque-needed features of all the mounts (the person at the booth told me finger-tight is okay… I’d personally probably give it a good 1/8 to 1/4 turn past that), and I figured out why. The recoil lugs are damn-near interference fit into a standard rail.

        If you like having your nice anodized rails stay nice and anodized, keep this in mind. That being said – I think a few scuff marks are well worth the benefit!

  • thedonn007

    What is proprietary about the spring? Are you saying that it only works with a certain brand of buffers?

  • Edeco

    GMO!? What about my fertility? *

    *kidding, I don’t really have an opinion about GMOs/fertility.

    • TheMaskedMan

      I wanted the spring too until I read that it uses a proprietary buffer. I’ve heard Damage Industries makes a buffer spring that eliminates twang, so that might be the better bet.

      • randomswede

        Just looking at the pictures I’m making the assumption that the inner diameter of the spring is smaller than the mil.spec. one and so the buffer needs to smaler to fit inside.
        IF that is the case many buffers could probably be turned down in short order by a competent lathe operator. (Assuming there’s material to take off and it’s not made from sintered pixie dust or prefabulated amulite.)

        • SGT Fish

          JP enterprises makes a polished spring that will get rid of twang. or you can just put a few globs of thick grease on the spring back behind the buffer, but that’s a cheap dirty trick. The JP polished spring has proven to work well for us, for a non-ridiculous price

          • randomswede

            Olympic arms makes a pneumatic recoil buffer replacing both spring and buffer.
            Can’t twang as there is no metal spring.
            No clue on how well it works, I don’t think I’d put it into a weapon intended for combat whereas the JP I think I would.

  • Blake

    If this stuff isn’t a dirt magnet I might try some on my bicycle chains…

    Currently I use Finish Line ceramic wet lube & it works extremely well.


    Would be interesting to see how it works on rifle parts…

    • Vitor Roma

      I’ve used the Slip2000 EWL 30 in the chains of mine with great results!

  • vorkosigan

    So… just canola oil then… with a 1,000 per cent markup.

  • Ken

    Black powder shooters have been doing that for probably a century. They know that petroleum based lubes gum up.

    • Christian Hedegaard-Schou

      Black powder shooters are using them as bullet lubes though, which carries an entirely different set of requirements than lubricating a firearm MECHANISM.

      For example, when lubing a mechanism you want AW/EP additives. Vegetable-based lubes almost never have these which means they simply cannot protect against wear as well as petroleum lubricants.

  • Phillip Cooper

    I’m calling BS. There’s no way in the world he’s gone and had a GMO product engineered specifically for him. You’re talking millions of dollars of investment there.

    He may well have had a lab cross reference previous work to find something suitable, that I can believe. But I still find it very doubtful he’s gone and had someone plant fields full of a special plant just to make gun oil (look at seed yield per hectare and then think of how much he’d have had to plant to get this “awesome gojuice gun lube”).

  • Sticky Fingers

    I know what Go Juice is really made of! Follow my impeccable logic here …

    1. “The Go-Juice is a bio synthetic lubricant made from GMO seeds specially made to produce this oil.”

    2. “It took 7 months to find the right lab that could manufacture the GMO seed used to produce the oil.”

    3. ALG Go-Juice is purple in color.

    We know all this from the article. I will now match each of the above (3) facts with evidence of ALG Go-Juice’s contents. Now watch as the truth is revealed …

    1. Marijuana is an organic plant with seeds (“GMO seeds specially made to produce this oil”).

    2. Marijuana has only recently become legal in a few States, therefore making the number of laboratories that could “manufacture” a GMO seed of marijuana very limited. Because of this, someone looking for a laboratory to make a GMO would require a lot of time (“It took 7 months to find the right lab that could manufacture the GMO seed used to produce the oil”).

    3. The liquids in the Duquenois-Levine Reagent marijuana field test turn purple when marijuana is tested (“ALG Go-Juice is purple in color”).

    Therefore, ALG Go-Juice is made from GMO MARIJUANA SEEDS!

  • That charging handle looks too familiar….

    • Squirreltakular

      I thought the same thing; then I realized that the AR-15 uses a similar one. Those things are everywhere.

  • Squirreltakular

    I don’t even care if the Go-Juice works; I just want a bottle because it combines two of a Liberal’s least favorite things.

  • Squirreltakular

    Well, I can tell you that that is a copy of the Axts Raptor.

    The point being, all charging handles look pretty similar.
