They ended up putting them on their web site... .578x28 for their .45's. I asked if they could thread it to 5/8x24 but did not get a response. Looks like an excellent host for my jailed Octane 45. |

.578x28 is the accepted threads for the 45. HK uses M16x1LH.
The only reason I use 5/8x24 unless specified is the availability fo flash hiders. |

To all of ya'll with grease gun mag lowers......I have found a little secret that solves a LOT of issues , especially the dreaded bullet nose up in the top of the chamber.....look at your mag from the rear, and look at the primer......open the feed leps at the rear of the mag.....where you can see most of the primer in the u slot in the back of the mag where the original grease gun bolt passed through.................... when you can see most of the primer , a lot of issues will go away.........

I have & it does help but there is a point we are missing. The CNC lower states it uses mags that dont need to be modded but they DO.  Feed lip mods & squeezing to fit. They can be a PITA to feed from. Now in this instance the gent lowered the center lug & may have removed all the suport.

Guess it is just how you look at it....if I can do it without a milling machine or special tools...I consider it adjusting..
 ........Hell, I remember having to adjust Grease Gun mags to get 'em to run for our recovery vehicle crewmen in 1/10 Field Artillery so they could qualify with their M3A1 Grease Guns....
and with the feed lip geometry we are milling with repeatability on the Haas CNC mill................................ keepshooting.com mags are pretty much plug and play......

And having to set a mag up on a milling machine and cut a consistent retention notch on a mag that is inconsistent by nature is.....???? It takes 2 seconds with a vice...or a c clamp or any similiar implement to solve the issue .....haven't seen that thread about the 6 mags but I'll check it out now....but if you talk to him.....tell him to contact me and I'll be happy to walk him through it...or if he wants to send 'em to me I'll adjust them for him at no charge......

Congrats...looks like a winner Ron...we just have different points of view....you don't mind setting up and milling the retention slot...and if you set up the way I do for the BAZ45 lower I have....then you squeeze them exactly as you would to square 'em for the CNC....
Glad to see your new lower running well....Here is one of mine on a standard lower with last round bolt hold open

USC Magwell adaptor test I have a jig that holds them for me. No squeezing here  My guess is you do somthing different. Setup, lock the jig in the mill & go. The cutting takes less than a minute.

Ron, how does your magwell dimensions compare to the AR45 lowers? Might just be that Justin uses tight tolerances that requires the mag to be closer to square. I see the same issue with some AR15 lowers on the market that accept some mags drop free but not others.

I pulled out ALL of my AR45 lowers yesterday and did some checking.....there is a problem with some of the latest production magwells. I checked mine from oldest to newest and the first 5 were fine as were the 80%'es I had in the safe...the last two 100%'s I bought I have the same problem....I fixed one with a dremel and cerokote .....and it works great...I called Justin and am shipping him the other one with a brand new Mag so he can formulate the corrective action. When the magwell was cut appearently either tool wear or one of the operators modifying with the program caused the radius on the back corners of the mag well to be too broad....simple to fix with a long reach 1/4 endmill or a small carbide ball and a die grinder.
Talked to Justin at lunch.....if anyone has an issue with a lower...shoot him an email and he will take care of it. If you are local to me swing by the shop and I'll help you out...............

I would stay away from the keep shooting because they seem to cause the most trouble with that lower. Just order some surplus & if they dont fit give them a gentle squeeze to fit. You just want to square them up. |

Yes, Rudy (Mad Machinist) helped me out bc I wasnt surw if it was the magazines or the micro-slick coating I had done on the bcg.
Rudy got me squared away with the mags and checked over my upper and has everything working smooth and reliable. I did end up buying 3 USGI mags but hadnt tested them out yet other than putting them in the reciever after cleaning all that greese off of them and making a small squeese to get them to fit a little better. I ended up throwing 3 of the 6 Keepshooting mags away.. but that maybe bc I bent them too much. I would like to thank Rudy publicly for always answering all my questions in regard to the AR45 endeavor. He has alwas answered my emails and phone calls promptly since before I decieded to have him build it and all the way until now. He has been following up with me after the build and its running great. Im also enjoying my first suppressor with it now as well. What a feeling! ;-) Next is exploring the whole .45 Super territory. .. hahha |

.45 Super is outstanding in the AR45 platform. I'm shooting 185gr that runs 1100fps in a 5" barrel. Not sure what the the velocity is in a 10-16" barrel, but it barks. Definitely changes from a pop pop to a boom boom.
I even built one for .45 GAP a few years back. .45 GAP is loaded to .45ACP +P levels and can be fired from Sten mags with the feed lips opened a little. Great conversion for a 9mm setup using Sten mags. I used a Thompson SMG barrel and had a local machine shop trim a little off the breach end before attaching the barrel extension. Ran like a raped ape. Sten mags hold 15-17 rounds of .45 GAP. Buffalo Bore Ammo has .45 Super in stock. |

I have done it & they work. You can only run 15rnds reliably. Alot cheaper than other mag options out there

Haven't read through the whole thread, but are any of the .45 mag well adapters drop-in for a regular lower? I would
love the option to slap a .45 upper on an existing SBR without the expense of having to get a dedicated lower SBRed... |

The .45 ACP in a double-column magazine will not fit into the AR-15 magazine well. You would have to use an UZI .45 magazine which is 16 rounds, IIRC. I suppose it is possible to use an AR-10 lower, but that would be a massive gun. Just buy an Thureon Defense Glock-mag gun. |

I think you missed the part where I said I want to use it with an existing SBR I'm not looking to buy a whole new
rifle or SBR another lower - I've got enough projects already sucking the bills from my wallet
I know of Rudy's USC block, but is it drop-in/easy-out requiring no mod to the lower? |

I'm saying that even with the tax, trying to get your SBR to work with single-column low-cap magazines is going to be just as or more expensive than getting another SBR set up to already take common, cheap magazines.,,, and you'll also have TWO SBR's in the end. |

Gotcha. You might be right. I may in the long run do that. I've got a precision rifle project that's going to consume most of my gun funds for the foreseeable future anyway, so I have plenty of time to decide on this 
Ron, if you're listening, do you give the option of having the lower of a complete build engraved w/ trust/city/state for future SBRing? |
