I should look in on this thread more often... Went shooting with Ron, The picture Ron posted of the Grease Gun modified
to fit into a standard mag well does it no justice. In fact, I may have the one in the picture... The mag performs flawlessly.
I asked about getting another and Ron's answer was "Why, You'll Never Wear The One Out". He's probably right, It's about
as tough as an Abram's Tank... They look a whole lot better than the picture too...

I also had one of Ron's 45 Win Mags with us. I think I found a Mag Solution for it. Still R&D ing but it looks promising if the
manufacturer doesn't fold the magazine line..... They are spring steel mags (Very Tough) and statically work great with a little
feed lip work and a modified Magpul Follower... The bolt hold open is very strong, following the last round.  More details if it works
out on the range...

How about GG mags without the block on the back? Did this using the same style setup as my uzi magblock. Just pushed the mag back about 3/8" to engage the mag catch with a solid block on the back.

Cool, but I didn't have a problem with them in a front feed format. So what
if the mag carries the block. Makes it so much easier to switch to another
feed format... Either way, Ron, you do magic with magazines...

@ Ron and Mad-Machinist.. You guys got the Idea (whether you know it or not) that eludes or is irrelevant most in these discussions...

those of us in CALIFORNIA do not have nearly as many options as those in "FREE-STATES" when it comes to (MIL Spec) .45 conversions by the simple fact that:

(1) any mag we use MUST either hold no more then 10 rounds or be MODIFIED to restrict mags to 10 rounds.. and (2) any center-fire rifle w/ a pistol grip requires some type of "tool" to release the magazine.

Having a MAG-WELL ADAPTER that still uses the AR15 mag release is (almost) a MUST to use the modified mag releases we allready HAVE to use ( ie: "bullet button" or "Prince50" etc.)..

A mag-well block somthing like the Hahn (Cav15 or 9mm Sten even WITH the modified for.45 mags) adapter wouldn't even cut it for us because i'd have to make ANOTHER "cali compliant mag-lock" for the lever on the adapter..

The new OLY mags are nice, but even if i wanted to pay that kind of money for them, they are HUGE and i have no interest in a magazine that is more then twice as big as the caliber stacked in it...

So for myself and the rest of us out here who stocked up on "off list" lowers because we figured they would ban them too.. I WILL NOT buy a dedicated lower for .45acp.. but am sure as hell determined to build one with a bitchen adapter for cheap mags modified or not... until I noticed you two gentlemen maintaining interest and still giving this a crack.. I just figured i'd have to do it myself..

Please let me (us) know what you got!!!! STEN.. UZI.. ( stripped GG) .. hell, any inexpensive common mag..  doesn't matter what mag because i'll find a way to make it 10-rounds..

any way to use milspec lowers with adpters and still use the AR mag release!!.. Then ill get fussy and wan the "open bolt" feature!!!

But really keep it up.. everyone of you that have taken this concept to a new level!

Cheers!

This is why I do the mag conversions. Not everyone wants or needs a "dedicated lower"
The new Uzi 10rnd mags are OK but they have alot more spring in them than needed. I have done a few conversions using them & sometimes you cant get 10rnds in them without some work. For the money I can shorten GG mags to hold 10rnds. Many do not care for the block on the back of the mag but it makes the mag a one piece unit. no need for a mag block. I am also working on mags to work with the bolt hold open feature

So I'm interested in this .45 acp AR. I have a 9mm AR15 and its a blast. I want a .45 acp upper since Michigan just legalized suppressors and .45 is perfect for that purpose.

I skimmed through a lot of pages in this thread and there's a ton of good info and innovation. I wanted to know has anyone every milled out their magwell in a standard aluminum lower to match the dimensions of the Cav Arms MK II receiver magwell so that it can accept the Hahn magwell  block for unmodded GG mags for the Oly upper / RMW upper?

It seems like a simple solution if there is enough aluminum left over after milling out the magwell. Would this work?

Unfortunately the magwell of a forged lower and a Cav arms are different enough that it would weaken the Forged lower to the point that it is unusable....I measured it once befor but I'll look at it again when I get to the shop in the morning....

I would say its a no go. Way too much material will need to be removed. I have heard of some setting up for thompson mags but you dont see those running around so I bet that is too thin also. You can use a stock lower with my converted GGmags.

Thanks. I don't have a Cav Arms lower to compare to. I was just thinking of this as an experimental / proof of concept project. My biggest concern would be that the magwell would be way too thin to remain structurally sound. I'd be willing to try it out on a "cheapie" lower if the measurements look possible.

Thompson mags seem cost prohibitive when compared to GG mags and the only advantage I see would be drums, which wouldn't fit anyways.

I double checked at the shop today.....it is a definite no-go.......While I prefer the CNC Guns AR45 lower, I build a magewll adaptor that works with the new promag Uzi mags.....10 round.....but I talked to my contact today and I have a preproduction 20 round model in the mail to modify and test, and it works in an unmodified lower with the above mentioned adaptor............and while I don't condone it.... LOL ......Ron does some extensive mods to grease gun mags for use in unmodified lowers.

Ok well thanks for checking. I grabbed some dimensions of the standard ar15 lower and it looks like to have my idea work it would be reinventing the AR45 lower concept all over again. I guess it would be more efficient to outright buy a pre made complete rifle in 45 or use the modded GG mags. Oh well.

I had issues with my last 10rnd uzis from promag. Couldent get 10rnds in them. Softened up the spring. Depending on what they want for the 20rnd it may be cheaper to do moded GG mags. They hold 28rnds without issue.

I had some issues with the promags not holding 10 either...what it turned out to be was the winchester whitebox I was trying to load....it was at the max OAL for the spec on .45.....everything else I had was closer to the min OAL and loaded fine....

It IS  something they need to address.....cause all the IMI mags I have load with no problem regardless of length.

Kurt Walla (RIP) machined a standard lower for Thompson mags. He refused to do them for customers as too much material was removed making it unsafe to shoot. I have a AR45 lower machined to take Thompson mags but the bolt carrier and the inside of the upper need mods similar to the AR47 lowers that take AK47 mags. A lot of work but I will finish one prototype and test it for function.

Slight advantage of T mags is 20 and 30 factory mags available. GG mags limited to 30 unless cut but the end user.

Here's my AR45 build:
CNC Lower
RMW Upper 11.5" + 5.5" Flash Hider
Magpul and other misc. parts

Put 200 rounds down range this weekend, runs like a sewing machine with reloads based on Ron's info and USGI GG mags, very accurate as well, I was able to punch quarter sized groups all day long at about 25 yards... beware of the keepshooting mags, the ones I tried need some more work (I had to remove the finish on them just to get them into the CNC lower), seems like kind of an art form to get them to run reliably.

Shaun315: Very sweet set up. Ron's Uppers are very accurate. I shot one 20 round group

For those who may be contemplating the purchase of the "new" Olympic Arms AR-15 .45 ACP upper/(polymer) magazine system, some comments.  I just got one and have only shot a few rounds through it.  It appears to feed, fire, and eject just fine.  I will do sighting in at a later date.  The only downside I found is loading the 18 round, single stack, single feed polymer mags.  I could only insert 4-5 rounds before the mag loading tool was required to produce the force necessary to push down the follower.  I do not have nor do I intend to get 10 round mags.  I personally doubt that a LULA type loader could be made to produce the force that is required to push the follower.  (I have a 5.56 AR-15 LULA loader that works well in that application).

Does anyone know if these mags ease up after some use?

Bottom line - if you are planning to buy the system, plan on buying the mag loader as well.

I am not affiliated with Olympic Arms or LULA.

Not legal advice, MHO, YMMV, etc.

The only benifit the oly mag has is the bolt hold open feature. Your story is the norm it seems. For the price of that mag I can comvert a GG to work with a std lower. Good for 28rnds & I load with my fingers. Toughest part is the first 2-3 & last 4-5rnds.
As stated above I also have these without the block on the back. I use a block that goes in the lower.

I made the first .45GAP blowback conversion, back in 2006, using a 16" Thompson SMG barrel and Sten mags. Used an Oly bolt and ejector. Had the barrel trimed a little off the back and the outside rethreaded for an Oly barrel extension. Local machinist did the cutting and rethreading but he took damn near a month.

Worked great and I sold it pretty fast but I never had any other orders. Go figure.

Anyone ever play with spring rates in .45 mags? Grease gun mag can be loaded to 30 rds with a little effort on the last 10. Oly new mags need the loading tool, but Thompson mags have a really low spring rate and it's easy to load my hand all 30 rds. Low spring rate with Reising mags as well.

I can see firing rate making a difference with weaker springs but I know of two builders that made an AR shoot with Thompson mags with no issues.

The thompson low spring rate is because of the double feed. Less required to get to proper hight. (please excuse if you know all this.)
GG is double that moves to single & is not that bad. I have reduced the tension on the surplus mags. The KS mags require no mods. KS has stoped using the paint they were using before so they should fit in the CNC GG lowers but I never had an issue with the Baz lower though.
Oly is a single stack & realy should not be confused with real mags.

Could not tell you. Never tested an oly 45. We could asume there would not be much diference but we know what happens when we asume

Yep any lower is GTG. Ron's nice little mag block is a tool free drop in and his Modified 30rndGG mags work great.

The Pmag thing is neat but its only 15 rounds and I wouldn't trust it for obvious reasons but it does run pretty well.

My block/mags will work with any lower.


Yes, but will they work with an Oly upper?


Nope. The ejector spring/pin would be in the way.

They can, I took mine and cut the rib out of the back of the mag and tweaked the top of the mag then welded a block to the back of the mag, I braved a block on one mag but it slightly warped it so I welded the others. It's time consuming and a pain in the ass but it works

Anyone ever built/seen a .45 AR using a side-charging upper?
