FOR SALE: Reising to Uzi Magazine Magwell Conversion GEN.2 IS HERE! 1/11/26

[bandanabandit1]

*I asked Dalbert before I posted and have his approval*

Tired of expensive factory H&R mags? Tired of not being able to get through a full magazine without jamming?? WELL, LOOK NO FURTHER!!!

If you are unfamiliar, these magwells allow owners to swap out their original magwell and in place use this magwell to be able to run newly manufactured ProMag .45 Uzi magazines. This solves one of the greatest issues with the Reising - magazine availability.

These magwells are designed to work on the entire .45 Reising family of models (50/55/60).

The generation 2 magwell builds on the feedback that I received from the original generation 1’s. Some of the changes include; use of a harder base steel, changes to the machining processes, improved slight geometry changes, and finished in a sleek black nitrided finish to improve surface hardness and corrosion resistance.

Just like the gen 1’s, these magwells start from a solid block of steel which is precision CNC machined down to the final product. Proudly designed, machined, and finished right here in the U.S.A..

From the beginning, I intended to design a magwell that had numerous advantages over the original. In the end I ended designing something that I believe improves on virtually every aspect over the originals. Besides tackling the glaring issue of original magazine availability, I wanted to create something more durable, something that had better small parts availability if a part were to break or wear out, a better finish and harder and thicker steel so users could get many more years of use from their Reisings. This magwell accomplished all of those things.

I am so proud to be able to offer this latest magwell, which builds on years of research and development at this point.

A FEW OTHER BENEFITS OF RUNNING MY MAGWELLS:

You can obviously retire your original magazines and magwell parts. They’ve lived a long service life, most magazines were produced in the 1940’s up until the mid 1950’s. That makes the “youngest” magazine approximately 75 years old. That is a very long life out of something considered relatively disposable. The ProMag .45 magazines are newly manufactured, cost a fraction of the cost of an original magazine (ie. $35 vs $250), and are easy to locate with a quick internet search. Additionally the ProMags carry a lifetime warranty on every magazine, any issues with them in the future just give them a call and they should take care of you. My magwells use standard military-issue Uzi parts (besides the taper pins that hold it to the receiver). These parts are significantly easier to find compared to original Reising parts - and appear to be more rigid and durable if you ever needed to replace or stock up on spare parts. My magwell also changes the location of the magazine release. On the original it is located on the rear of the magwell whereas mine moves the release to the left hand side. So you are able to press the magazine release button with your left thumb and pull down on the magazine with your left hand to have a much quicker and easier magazine change. On some of the originals you had to pull back on the magazine release lever and then pull the magazine down - basically a two-handed operation. Lastly magwell is about 2.5x the weight of the original (~12oz vs ~4.7oz), this increased weight adds a nice balance to the center of the firearm and also aids in control and recoil mitigation.

OTHER THINGS TO NOTE:

From the beginning when I was gathering dimensional information from other Reising owners it became apparent that there is a wide range in dimensions/tolerances between Reisings. I took this into account and designed a tolerance range into my magwells that should be compatible with as many Reisings as possible to make my magwell as much of a “drop-in” improvement as possible. With that, I still want to note that there may be some minor fitting required - primarily the width of the magwell cutout in the stock. I have no received any mentions that the magwells themselves had to be modified at all. You can measure your magwell cutout in your stock, the width should be about 1.20” for the stripped magwell to be able to be slid in and out of the stock. I have included a how to guide at the bottom of this if you think you would need to do this. When installing the magwell please note that it should be stripped (no magazine button assembly installed) until it is in the stock - otherwise it will not fit through the cutout. Before altering your stock, I recommend installed the new magwell to your action and cycling a few snap caps (DON’T USE LIVE AMMUNITION for safety reasons) through it to verify that it is compatible with your particular gun.

Also, some users have noted that in some cases the magazine lips on the Promag magazine may need to be slightly adjusted at about the last 1/8” so the round strips off and feeds into the chamber. This takes about a minute with a pair of pliers. See guide at the bottom for how to complete this. I did not have to do this in my particular Reising.

If you wipe down your magwells with a clean patch you may notice a slight orange-ish color - this is normal. I reached out to the facility that did the nitriding and they confirmed that this is from leftover particles from the nitriding process. It is nothing to worry about.

Expect light machining marks on the magwells, it is all cosmetic. See photo at bottom.

The area at the top of the magwell that pins to the bottom of the action bar is designed to be thicker than the original. With this I also redesigned the taper pins that pin the magwell to the action. I used a tough 300 series stainless that will provide better wear and rust resistance over the factory originals. There is a small chance that you may need to fit the taper pins to your particular gun if they are too tight to install/remove, although I did not have to do this in mine and other have reported the same.

Lastly, please make sure that you do not try to insert a magazine into the magwell as soon as you remove the magwell from the packaging. The spring and magazine release button are not installed in the correct position so there is no tension when you remove them. If you try to insert a magazine you WILL BEND YOUR RELEASE BUTTON SPRING.

If you have any questions or concerns, please feel free to reach out to me and I will be happy to assist. If you think you need to modify something or are unsure of how something should be installed, please contact me before you do any modifications. Once you begin fitting/modifying your magwell, it is yours, I can NOT accept it as a return if you decide you don’t like it or no longer want it.

I’ve tested numerous magazines and can report that they have all functioned 100% flawlessly. Other Reising owners have reported similar stories back to me (once everything was tuned to their specific gun). In some cases my magwell will even help make your gun run more reliably over the original.

Finally, I’d like to take a second to thank all of the Reising owners who took the time to help me gather information in the early stages and support the final product. Your support directly allows these innovations to continue!!! THANK YOU FOR SUPPORTING ME AND MY IDEAS. I have more exciting things that I am working on to roll out in the future. ***PAT. PENDING***

Blemished Magwell assemblies (I have 1 available), includes same parts as above. The reason that I am calling these blemished is that I buffed these ones a little too much - markings may be lighter (particularly the “R” in Reising on the one), but both will function just fine. $405

Shipping and Insurance is NOT included in the above prices. I will use the lowest cost shipping method by default unless the buyer would like to purchase a different method - typically USPS Flat rate.

Methods of payment;

I accept personal checks, USPS MO’s and CC’s (I use Square as a processor, they add a 3.5% processing fee - I send you an invoice through them and you securely input your CC info - I don’t see any of it). Orders will ship after your payment clears, typically 3 business days. PA residents please add 7% sales tax.

Troubleshooting

Here are some of the common issues I've seen and the solutions for them. I will try to keep this updated as I gather feedback from users.

Magazine is hard to load to full capacity. Solution: Load the magazine to full capacity (or as many as you can) and leave it loaded for a few days to compress the spring. I've noticed that the springs get considerably easier to load after a few range trips. The first time I could get maybe 20 rounds in, the next time I was able to get the full 22 loaded. Also isn't a bad idea to disassemble the magazines and clean out the factory grease from the inside - there's usually quite a bit.

Bolt isn't stripping the top round from the magazine (typically the most common issue - ProMag changed the feedlip dimensions of their current mags). Solution: So it was brought to my attention that the most recent batch of ProMag Uzi magazines had slightly different dimensions in the feedlips than the older ProMag magazines. Luckily, it is a very quick and easy fix. Please see posts # 6 & 7 on the link below from a customer over on UziTalk. Basically the feedlips on the newer magazines aren't as wide as the older ones, so you will need to slightly bend the front portion outwards so they are about .455" wide from lip to lip for proper feeding. Once he made the adjustment they ran perfectly! After measuring the magazines that I used in my initial R&D I discovered that I was running the older magazines, and thus why I didn't experience any malfunctions from the magazines. Link on how to do this https://imgur.com/a/rnlpfnr Thanks Garrett on UziTalk for providing this guide.

Magazine release button is hard to press in to remove the magazine. Solution: Grab the empty magazine with your left hand and push up, while pushing up press the magazine release button and pull down. This takes the pressure off of the magazine release button and makes for an easy removal.

 

I encourage anyone who purchases a magwell to not hesitate to contact me if they experience any issues and to share their feedback with me. I am more than happy to assist and get you up and running!

Thank you Chappy! I'm glad others appreciate my project, a TON of time and learning went into this. Hopefully this does solve the biggest issue for the Reisings in regards to magazines...

All my luck LOL   I wish I had not bought up 5 oem mags and 3 christys before you came up with this retro fix !   I would have saved a lot of money. (crying)

Thumbs Up ! Great idea. For the price of a single OEM 20 round magazine you can use available and less expensive mags. 

Made in USA, so what's with metric dimensions ?  The King's thumb not good enough for you ???

That was the plan! And they don't make inches that small!

I received mine a few days ago and it took only about 10-15min to install.  It is very nice looking and way, way more sturdy than the OEM magwell.  Directions and videos made it very straight forward.  Luckily, my stock did NOT need sanding...it literally was plug and play!  I did several 22 round mag dumps in a row and the magwell is a champ!  I was quicker at changing mags as well.  Great new addition/investment for my Reising M50!

I got mine today.   Excellent quality, built like a tank, great guy, fast shipping and looks like a breeze to install.  Can’t wait to get it up and running and love being able to have an alternative to the original mags.  Thanks Erik!

Sure do!

Free bump with a VERY positive review for this product.  Fit snug but no change to wood required. Adjusted feed lips on NIB Uzi mag ever so slightly (per instructions posted online) and it ran great EVERY time that I shot it.  Great job!

Time for a long awaited update....I received the latest batch of magwells from the machine shop that I have been working with on Wednesday, I did the final surface prep and sent them off for the final step (heat treating). They should arrive there early this coming week and I was quoted about a week turn around time. I expect to have them back in hand and finished by Dec 8-9th and will begin taking orders a day or so after that once I have them all oiled and packaged.

If you have reached out to me in the past expressing interest in picking up one, there is no need to reach out again. I will be contacting everyone in the order that they reached out to me, starting with the longest first - I will be doing this once they are ready to be shipped in the mail to you all.

If there are any new questions regarding the magwells, I encourage anyone to ask here and I will be happy to answer. This latest batch of magwells are the nicest ones yet. I think everyone will be well pleased with them.


And again thank you to everyone who expressed interest and wanted to support my project. You are all helping directly fund future Reising projects that I plan on creating.
