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. |

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. https://c3junkie.com/?page_id=841 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. If you refresh your browser here on AR15.com's homepage, you will see that the main banner ad is for: https://hydraweaponry.com 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.

I'll give Justin at CNC a call this week......AR stuff and the lowers are pretty much a side gig for him......He is the programmer and lead machinist for a fairly large family owned CNC production shop. Just sent Bruce at BB a text.

What kind of upper???? If Colt style blowback, Bazooka really is your only compatible option....I designed an ejector insert for Bruce that is bolted into the lower....and because of the Md position of the mag it will run with blowback or DI/RDB. If you send mags to Bruce he will cut the retention notches. Be aware you may need to have the bolt converted to controlled feed and have the feed cone recut.....I KNOW Macon Armory stuff will run on the Bazooka....but I have a feed cone that is significantly different than the rest of the industry.

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.

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! |

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. Scott |

The CNC is ONLY compatible with DI45 or the Rotary delay........Bazooka Brothers is compatible with the colt pattern blowback and runs well with the DI and RDB as well. CNC uses unmodified GG mags.....retention notch has to be cut into the mag for use with GG mags. I have both and have tested our products on both.
