| I've had my .45 DI kit for a few weeks now. It's awesome! Got a few go fast parts I'm working with which is requiring some additional work to keep it reliable. But so far it's been great. I'll have pics and a write up in a few weeks. I have a carbine match at the end of the month I'm itching to take this to. |

I prerer not to do the kit on DI.....They can be finiky.....BUT I will be happy to use customer supplied parts to reduce the cost....give me a call at the shop....

So many options now!!!! I must be old!!!!
Choices, choices.... Grease gun mag well or Glock 21 magwell..... I have GG mags since I have a CAV15 w/ Oly upper. Yet, I also have Glock 21 mags..... (and want a 10mm DI upper...so the Glock is tempting...) Yet I have an old shelved 7.62 Tok project.... have a magwell adapter I got from someone here YEARS ago using unmodifed PPSh43 (?) mags (curved with a rib on the back)..... It was way back when people were having the debate blow back Tok vs gas Tok.... really need to finish that (aka get a Tok upper) I just retired my regular 9mm Colt style adapter and got a dedicated mag well. Always had issues with the adapter and mags (this was before the sunset of the 1994 ban in 2004).... Walked in to a store, saw the dedicated 9mm AR Colt type mag was on sale (much cheaper then buying online, shipping, transfer fee and "use"-aka sales tax). From what I see, most are going to a Glock type AR lower... which I might do for my 357 Sig blow back... feeds much better in a double stack/single feed (anyone remember the old, old Cold 9mm AR South African type mag, kinda like a grease gun, but not...) the the OEM 9mm Colt double stack/double feed.... Now I know why I faded away from here.... the temptation!!!!

Been wanting to pick up one of those old Commie pistols that look like an old Colt 1903(?)...the TT33(?). They say they are a bit better then the CZ52.... oh well. (I've got a 22TCM/9mm Rock Island and a FN57.... a 22TCM9R chambered 9mm PDW would be interesting....maybe). Kinda went off on a tangent here from the 45 ACP topic..... |

Back in the day, the creators of the BOZ said Govt/LE only. Everyone wanted to copy and chamber it and use it in their 10mm (well, folks in the US)... but there was a patent or something. I never heard of anyone making a chamber cutter/reamer for it....let alone dies. If did, it was on the QT.... Looking at the links now, it looks like the Boz was modified to a 9mm case, but their top end was 1700fps. I never knew of the 9mm tests.... not sure what the status is now. Story here: Story on the 224 Boz Fast forward to today.... ya have the 22 TCM which Rock Island sells in a 22 TCM/9mm combo. And their 22TCM9R, same case as the 22TCM, just shorter bullet loading/different bullet. The 22TCM I think has an OAL just under a 38 Super, as the double stack mags are similar to the old Para Ordance double stacks.... But it is kind of like the 224 Boz.....well, the 9mm version of the Boz. I'm sure a 357 Sig necked down to accept a .223" bullet would be similar, depending on bullet weight..... When the 357 Sig came out, a whole BUNCH of necked down rounds came out. The 400 Corbon, 40 Super, there was a .380 necked to .32 cal called the .32 NAA and then the .25 NAA- 32 ACP case necked down to .25 cal. (I looked at the NAA site, shoot, they still make the 32 NAA!!!!???) |

| Yeah, I looked @ the .224" Boz. Think one version was based off a .45" case. .22" TCM seems pretty slick; it would be nice to have a little more case capacity, but still fit a few more rounds in a pistol than a double-stack .45". |

Back to 45ACP talk :D
Bought the upper from a local fellow. Came with mag block and 30? rd single stack Promags. Was told theyre USP maybe USC? I shot maybe 15rds using another pistol lower. Had some failure to feeds. Im goint to list them in the EE Tried with the QC10 lower with similar results. Did some reading here but photobucket puking made it a little harder. Removed weights from a spare buffer. Was using a 2.66 OZ buffer & standard carbine spring. Rock River 2 stage varmint trigger. Had to do minor polishing to bolt lug & gas tube at the bolt port side, checked gas block to port and gas tube alignment, re-shape the extractor points similar to 458Socom. That experience came in handy. Made the action smoother and eliminated the scratching of the brass body and base. Modified the mag follower & also the contact pad of the BHO lever to clear the mag body. Will post additional pics later. 5rd group at 50yds at 4X. Will have to return to the range to test the function after modifications.

That is definitely one of my USC mag adapters.......call me at the shop...I have a program for owners of the USC adapter to get the new mags and adapter at a reduced price. If you want to run on the Glock lower...I have a new feed cone design that I should be able to retro fit if it is one of my barrels. ......not sure if that is one of my uppers but I'll be happy to assist anyway I can....the handguard isn't one I remember ever using......and I did sell a lot of the USC adapters as stand alones. Look at the bottom of the bolt carrier.....it needs to be modified to clear the USC feed lips....failure to do so can cause failure to feed.

Hey Rudy,
I have the USC adaptor and 2 mags listed for sale. I should pull them if there is an issue & I dont want the buyer to have problems with them. I did not get to use them in this rotation. The upper is from you. Seller forwarded the emails from when he sent it back and there was a bolt exchanged. He is jobsonad from Virginia and the sale of the upper was from Wed, Dec 31, 2014 at 10:52 AM according to the receipt. This recent session was with the QC10 Glock lower. Getting some failure to feed & sometimes failure to lock back on empty mag. Loading only 3 rds to get optic dialed in. 3 Glock factory mags. 1 mag has weak spring so that didnt count. Another Glock mag has Kriss extension. Was using Federal 230gr FMJ & Geco 230gr FMJ. No difference Inspected BCG & noticed a couple of things. The 2 bottom lugs are relieved but Im seeing some signs of brass. Does that area need more chamfer?  A minor feature at the rear of the carrier where the ramp has a step. I have a spare carrier to test next go around  The charging handle has strange wear. The bump is worn down & not as tall. I dont know if your uppers include a charging handle but I will be replacing that from my spare parts  Here's the weird part. At the end of the session I got frustated so loaded a full 13rd with a random mixed load of the above with my reloads and 185gr Wnchester hollow points mixed in. 3 different mag full. Did a mag dump at 25yds. No failures to feed. Lock back on empty each time. !!! Dont make sense to me but was impressed with the grouping at 25 yds. !!! Pics are upside down =/ 
|
The reliefs in the bolt carrier have to be there to clear the feed lips of the USC mag due to the angle it installs.....if not present, it'll never feed.....the odd cut on the ramp transition....not sure how that got there...I can assure it wasn't there when it left the shop...if you like give me a call at the shop....and I'll go over all the options I have available to update your system....
QC10 can be iffy as the mag has a tendency to float on the mag catch .....as it is significantly narrower than the slot on the mag. Cutting .035 off the top of the mag catch can improve feeding in some instances as well as working on the over insertion stop....also look and see if the bolt locking lug is hitting the steel insert in the magazine at the rear....may need to do some clearance work on the carrier as well.....if you like send it back to me and I'll be happy to give it the once over and update any features that have had significant change.....Just cover shipping and any updated parts. If something is replaced due to wear that is covered at no charge. |

I know I'm late to the party and this thread is actually TEN years old! 
Can we have a current wrap up of what is available in regards to GG mag lowers, and .45 acp uppers? 80% lowers anymore? This thread is great and all, but out of date and a bit long. Thanks guys! Help a brother with a stack of GG mags find a new host for them. |

Help a brother with a stack of GG mags find a new host for them.  so DI 45 (www.maconarmory.com) or Olympic Arms K45's are the only option. GG mags will also run with our DI and Olympic uppers on the GWACS Cav Arms lower with a Hahn Grease gun adapter.....not sure if Dustin is still making them.....but they work great.Several Glock lowers for large frame Glock mags exist now now...QC10, New Frontier, (and it various rebadged versions like Spartan, Joe Bob's and Palmetto State) and my favorite, Angstadt Arms, but obviously won't work with GG mags
Olympic arms is closed, but you can still order parts last time I checked....and I have heard talk of a resurgence....and Macon Armory is still the only production Manufacturer of DI45 uppers, and my personal CNC lower guns have tens of thousands of rounds through them. Feel free to give me a shout at the shop......Rudy |

The CNC GG lower with an Oly Arms blowback upper is stupid simple and ultra reliable, even with the funky ejector spring. But you still have the drawbacks of a blowback system. Heavy bolt movement affects recoil management and getting back on target speed. Bolt bounce can be an issue but a heavier buffer can fix that. Olympic Arms is still in business but most items are made to order. But if you shoot a blowback gun and them one of Rudy's DI guns, it will take a week to get the shit eatin' grin off your face. The difference is a sight to behold.

The difference is a sight to behold. I'm hoping to fab and or build as much of this as possible, I really enjoy building as much as I can. I've also been considering making an upper using a 16" Ruger Ranch Rifle barrel like i did for my MAC10. |

They'd probably sell you a couple cheap - they've got $5 or less in em. Not me - I gave my $5 lowers away for Christmas presents. |

Thanks Rudy. Many props to you. Thank you for answering my many questions when I called. Great to talk to someone very knowledgeable and willing to share. I was able to fix the stuff we talked about and glad I didnt have to send the upper back. I think I want a shorter upper. 8 or 9 inch maybe. I dont wanna cut this one down. Is there a barrel, BCG, gas block builders kit available? I have a capable mancave full of tools and have assembled many 458Socom, 556 7.62X39 DI & 9mm blowback uppers. Guys who are reading this - if you are looking for a DI upper get a Macon Armory upper. |

Rudy - I'm new to the .45 game but have built several, including a 9mm dedicated suppressed.
I want to build a similar in .45. I have a stripped lower coming from Karri's Guns to start. I dont want to build an SBR, but since the suppressor will be permanently mounted, I want a short barrel, no longer than 7" (Form 1 can is 12") to make it right at or just over 16" Do you have anything that would work? |
|
Give me a call at the shop, I can make whatever barrel you need...........478 474-2990
If planning a blowback... I have 5 inch uppers on the shelf.....and I can shorten an 8.5 if necessary, or make you a special from a blank. |

I tried every carrier finish, Melonite, FailZero, NiB+Teflon, and even high temp lubes(like Krytox XHT-BDX) but still only get a few mags before the bolt/gas rings locks up. The ol' mil-spec chrome gas cylinder runs the longest, I use an adj gas block and a 1/2 weight Carbine buffer and a worn out old buffer spring. I run Federal +P HST's at just under supersonic, and always get curious look's and questions at the range(it's such a smooth shooter). Just wonderin' just how long yours shoots "smooth as butter"? :) |

Over 250 rds of factory & my reloads with no cleaning and no failures to feed or eject. Will continue to test shoot without cleaning until I get 2 failures.
The locking lugs had very sharp corners and needed chamfer. See the lug inline of the ejector. And at the "3" of 3M The rear contacts needed it more than the front but I dont like sharp corners as they are stress risers. Compared this bolt to a 556 JPrifles, a piston LWRC & a Teppo Jutsu 458Socom to see where it needed work. 
Cut back 1/16" from the bumper to make LRBHO reliable. Read somewhere the SB PDW buffer is shorter

Im using Unique powder the recipe given to me by a mentor reloader many years ago. Didnt find a need to even tweak the powder weight as it shoots great in my 1911s & Glock 21 to a Mechtech upper I got rid of a long time ago. 230gr Rainer or Berrys
I use Bullseye or 231 for cast lead |
| I've read this thread and I'm very interested in building. Cnc45 lower and a macon armory di upper work together if I'm reading this right. Is there any way I can get a bare bones upper without the rail and muzzle device? Are the upper receivers proprietary? Thanks for your time and this amazing source of information. |
|
Call me at the shop,478 474-2990 ......the thing about forearms is not all are compatible with the gas system.....let me know what you want to build and we'll help source something that meets your wants/needs, and you are correct...the Macon Armory DI45 was originally designed with the CNC AR45 lower as the only platform for it...I still have my prototypes...
