I've seen a couple mentions here and there of "lower that accepts Grease Gun Mags".
Searching, all I found was reference to some abortion that used a GG magwell bolted on to an AR rear 3/4 receiver.
Is there a stock, from the factory, AR lower that accepts unmolested Grease Gun mags?
Thanks.

Maybe these guys?

Bazooka Brothers.

CNC Gunsmithing.  I bought mine from Macon Armory, not sure who sells them now. Make sure you can get your hands on grease gun mags, they were starting to get scarce when I built mine.  The lower has a special mag release, mags are unmodified, except for a slight tweak on the feed lips to get the bullet angled correctly.

Hopefully CNC is still making them or they are available from someone like Macon. Both of mine are fun to shoot and always a favorite.

I think the Cavalry Arms plastic lowers (and their descendants from GMACS and KE presumably) take Grease Gun mags but require a mag block. They have a widened section in the well to allow the fatter mags.

ETA: I didn’t realize this is the pistol section, obviously those would have an integral stock so they might not apply.

I have an MGI Modular lower which I think came out in 2004.  Back in the day you could get a bunch of different magwells including one that accepted unmodified GG mags.
Here is an old pic of some of my magwells:


Here is a link to my website discussing my .45 CMMG RDB setup using my MGI lower running in full auto.

Note that the mag release is in the same familiar spot.  I like how they also do that on their AK magwells instead of the flapper style.

So looks like they are trying revive it and I was hoping they would bring back all the great magwells.
I just checked and they now have an MP5 magwell which they never did before.
So maybe someone can convince them to do the GG magwell again.
I was hoping they would do a Scorpion magwell to have the MP5 look but add LRBHO.

ETA:  wanted to clarify that the MGI GG magwell uses Unmodified GG mags

mine is the bazooka bro's version.
it has a derlin tab that is held in by an allen screw.
with that tab in, gg mags lock in to the magwell.
pull it and it takes standard mags or adapters.
I got mine from ron williams, but it was a complete gun.

Not sure such a thing exists. I have a 2nd generation Bazooka Brothers that takes molested grease gun magazines.

The CNC Gunsmithing lower does/did use unmolested mags. I tossed the past tense in there as it isn’t clear if they are a still available.

If anyone gets ahold of CNC guns, I want a couple of his A1 carry handles.

I sent email to both BB and CNC, nothing from them, yet.

"rimfire and pistol caliber" subsection , you're fine.

CavArms lower with a Hahn magblock

That's really interesting, but, I have an 8" barreled upper, and they only sell "rifle" lowers.
Not looking to SBR or extend the barrel to 16", if even possible....

It's CMMG barrel and bolt, I already have the GG mags.

That is identical to my setup I posted above.  8" CMMG RDB.  The MGI GG magwell is designed for straight blowback so it has a fixed ejector that I had to remove but surprisingly, I didn't have to mess with the mag height at all.  Removing the ejector is all I had to do.  Hopefully https://hydraweaponry.com/product-category/interchangeable-magazine-wells/  brings it back.  I think that system has so much potential.  I would rather SBR one lower and have multiple magwells myself.

This is what I have also, I SBR'd my lower years ago as a 45acp, currently only have the GG and standard AR magwell.  Looking for an AK magwwll......

There are plenty of AK 7.62x39 magwells out there...it is the AK 5.45x39 magwells that are hard to find.  I have (1) 5.45x39 and have (3) 7.62x39 from several deals over the years.

Should i be offended?

I have a couple of very early Bazooka Bros lowers, like single-digit serials. I put the first one together when Olympic Arms (the only player in .45 at the time) had run completely out of the Uzi mags they had been using. The BazBros lowers require a cut on the side for a mag catch so they use the same mag catch as the AR, and they have run flawlessly for more than ten years. His first ones were I think DoubleStar lowers with the mag well cut away and the new well mortised and tenoned in place-- actually kid of hard to see unless you're looking for it. Would I buy another? In a heartbeat, if the State of Washington would only permit it.

Love my CNC 45.

You have 3 x39 magwells now?  No one needs more than 2........I'm interested if you wanna sell one.

I love mine also, one of my favorite guns. SBRed with an Olympic upper that was modified and has an integral suppressor.

That one was finished by Thompson Machine.

My first lower was finished by Khalan Weaponry and was too out of spec to be used. Even after sending it back and him. It sits on my work bench as a reminder to be very cautious doing business with unproven fly by night outfits.

Ah Khalan Weaponry. The first blind and retarded gunsmith/mfg I have ever dealt with.

Thankfully M60Joe was able to correct the worst of the problems and a member here fabricated some other small parts that ended up working.

I remember cnc guns from when it was just discussion and drawings. It inspired me to buy a dozen mags just before the market went crazy on them.

I did modify a cad file of a ar lower to fit a GG magazine.
I partially machined it, never finished it cause I didn't know what to do about the mag release.  
I also 3D printed one years laster, but not at strength settings. Still no mag release either.

I have the olympic arms 16" upper. Came with modified 10 round uzi magazine.

I also tinkered a bit, squeezed the upper portion of a grease gun magazine in a vise to fit in a regular AR maxwell, welded a tube to the back like the uzie mag, and it worked!

THAT. IS. SO. COOL!
In all fairness, the pics I saw of the one BB lower probably was a prototype, it did not look "finished" in the least.
That is a neat looking gun.

GWACS yes, as they're selling the Cav Arms Mk 2 lower.  KE Arms no, as the KP-15 magwell was designed to run modern mags, including the MagPul Gen 2 that the Cav Arms magwell struggles w/.

Hahn makes the mag block for the Mk 2.

No reply from CNC Guns or Bazooka Bros.
Still looking, but a little surprised there aren't more manufacturers making GG lowers.
Doesn't EVERYONE want what I want?

I want the side feeding upper that takes Thompson or GreaseGun mags.

Did you try hitting up hydraweaponry.com like I posted above?  They have an ad on the main AR15.com banner page now so they are trying to get business.  My buddy saw them at Shot but didn't ask about the GG lower since both he and I have that magwell so didn't ask.  Since they made it before, I would think they can make it again.

I also got a GG/STANAG lower from Ron, though the lower had his RMWX info on it as the manufacturer. I got it with a DI .45ACP upper and he has since built me a 10mm upper. Had him modify 5 of my 10 GG mags to run 10mm.

Makes me want to get a 10mm M10 upper now so I can use the 10mm GG mags on a MAC10

The Hydra Weaponry site https://hydraweaponry.com/product/hydra-ak-47-modular-magazine-well/ the AK-47 magwell for $275.00 plus shipping. They used to be at mgi-military.com, but that brings you to the Hydra site. I noticed when Windham Weaponry sold out (they also sold a version of the modular magwell lower, MGI had dropped their price for magwells from $250 down to $125. While still pricey, $125 per magwell is reasonable.  But they only had the standard,  9mm Colt, andAK-47 magwells.

Like"amphibian" I think that the modular magwell concept has a lot of potential, $275 per magwell is just too much money. Most any of their magwells have a complete lower receiver in the market for half the money. So for the vast majority of semi auto collectors, they can buy a complete lower for less than the cost of the Hydra magwell.

I find it odd that they didn't learn their lesson from 20 years ago. When the MGI modular magwell system came out a stripped lower with a standard magwell was $500.00. Now the stripped lower without a magwell https://hydraweaponry.com/product/hydra-modular-lower-receiver-only/ is $125.00. The stripped lower with standard magwell https://hydraweaponry.com/product/hydra-modular-lower-receiver-w-5-56-mag-well/ is $374.00. I think they have this backwards. They should make the stripped lower the expensive part and make the magwells less expensive. At $125.00 or $150.00 per magwell, if you have the registered part, then adding another magwell is competitive with a complete lower,  so Hydra makes a sale. With the current price structure very few will bother with the Hydra system at all.

As near as I can tell Hyra's management has not changed from MGI. Their price structure has not really changed either. So it seems like they got an infusion of capital, but are following the same basic model that they started with 20 years ago. They seem to be bringing some new magwells that they can patent, but they seem to be going down the same path.

There certainly would be interest for those interested in NFA applications, such as SBR or a host for a DIAS or LL. Certainly having one lower having a special trigger or stock/buffering system would have some interest in not repeating the specialized parts for multiple lowers would also have appeal. Is the modular magwell system cool?  I certainly think so, especially for NFA applications. OP, good luck with your  .45 project. Like "amphibian " I have a Grease Gun magwell and a custom built Thompson magwell with last round bolt hold open. I would suggest contacting Hydra about  .45 ACP magwell availability.

+1.  I agree on the pricing.  Also wanted to point out that I do like how MGI / Hydra retained push button functionality on their magwells, so a familiar push button for the mag release and not doing a flapper for AK mags or GG mags.  I would hope they would continue that for the upcoming Scorpion mag well.  
I don't like how they didn't do LRBHO on the Glock magwells but they told my buddy at Shot that they are going to be bringing the Glock magwells back and this time have LRBHO.

Seems when I read your post earlier, I read it as they no longer manufactured the GG lowers. Tried going on to their site from the page here, I get a metric boatload of warnings that their site will give my computer herpes or some other shit.

I see this on their contact page:

Note that my buddy that went to Shot told me to email Tanner which I did but haven't heard back.  I didn't try calling him nor did I try the main number.

Mucho thanks.
Just curious, when you go to their site, does it kick up warnings with McAfee? Wonder if it's just my computer and the security settings we have on it.

I don't have McAfee, not getting any warnings about NoScript.

With my computer, the Hydra Weaponry website front page is okay, but any attempts to reach the next level down is flagged as not secure and blocked.

MHO, YMMV, etc.

I have a GG magwell for my SBR'ed lower.  What uppers are you guys running?  I am using an old Olympic Arms blowback upper, I'd like to run a DI upper if possilbe with GG mags.

If you are saying you have an MGI GG magwell then it should run fine with a CMMG RDB or Macon Armory or RMW by just removing the ejector in the magwell.
As I posted above, I currently run a CMMG RDB in .45 and used to have an RMW .45 gas operated as well.

I wasn't clear, sorry, yes I have a MGI GG magwell

Are CNC and Bazooka Brothers still doing GG lowers?  Neither site looks up to date.

I talked to MGI at NRA a few years ago and they claimed back then that they were bringing the GG and Glock lowers back, but nothing ever happened.  I really like the idea & system.

Edited so we can stay on topic.

Thanks for chiming in.

Please OP.....call the manufacturers up, and update the thread with any information they provide to you, and share it with others in this thread.
Some good folks have tried to help you out by pointing you in the right direction

It would be awesome of you to provide that information for others to have available to use as a resource.

Thank you in advance for any information you can provide in your thread to help others.



Edit.....this was a friendly and honest attempt to keep the thread moving with information from any manufacturers.

Congrats, I didn't realize you had been elected Hall Monitor of the Pistol Caliber Forum, and thank you for stepping up and white knighting for the "folks subscribed to the thread" looking for information that are apparently MORE communicationaly challenged than I, and have been waiting with baited breath for my latest update.
