Reising to Uzi Magazine Conversion Magwell - a fun project I completed
- Thread starter Bandanabandit1

They still work for me, although I haven’t used them much in the Uzi. I mostly use the grease gun lower if I’m shooting .45 in that gun. But the handful of times I’ve used them they still ran.
I'll send you a message.
Hello from WV. I have a Reising M50 that has been a pain at times. It would shoot perfect and then only shoot single shot at times. I have gone the route ofm replacing parts one at a time as well as starting with all new springs. One time it was the action bar and the next time it was springs. Currently it is running great. Also I fortunately acquired 3 Christie mags with the gun, purchased several 20 rounders, and even traded 5000 primers for 3 20 rd mags. So I am well set up with mags having 11 20 rounders and 3 30 rounders. With that being said i still am interested in your conversion and would like to obtain one if possible. 20 rounders are going for 200+ and Christie's are 300+ so I would like to shoot a cheaper alternative as I won't be able to replace my original mags. Please pm me sith any details concerning obtaining one of you conversions.***PAT PENDING***
Hi everyone, I thought some of you would enjoy hearing about a recent project I have finally completed that I started earlier in the year with just a concept. Like many that are familiar with the Reising family of firearms (M50, M55, and M60) you are probably aware that one of the BIGGEST complaints is magazine availability - there just aren't a lot of magazines around. This problem planted a seed that turned from just a concept in my head to an actual product (that works!). I wanted something that would solve the issues of trying to find some original magazines (good luck, and not to mention the price) or trying to jerry-rig a modern magazine to fit in the original magwell and hoping that it will function reliably. I present to you - my Reising to Uzi magazine Conversion Magwell.
This magwell is CNC machined from a solid piece of steel and later hardened for superior durability. I set out with the goal of creating a magwell that will not only run (and run and run) but will also utilize modern machining and heat treating processes to make a product that will last - compare this to the nearly 80 year old original H&R magwells that are just blued steel or parkerized. While comparing, you will see that the magazine release is also much improved over the original factory method of releasing a magazine. Simply press the button with your left thumb and pull out the magazine - as it should be. This is especially true on the earlier Reisings where you had to pull back the magazine release lever and then pull down the magazine.
With the issue of magazine availability (and parts for that matter) at the forefront of this project, I carefully considered what magazines I wanted to make as the foundation of this project. I settled on newly manufactured .45 Uzi magazines from ProMag. From all of my testing I have not had a single malfunction induced from the magazines - and I tested quite a few. Not to mention that ProMag also offers a lifetime warranty on each magazine! Once this magwell is installed, it is essentially "Plug-and-Play" - you can just insert a standard .45acp Uzi magazine without modification and you're ready to go. As you can see the advantages over the original H&R magazines that are almost all 80+ years old is something significant to consider. Aside from that, the parts used in the magwell assembly themselves are widely available if someone wanted to pick up some replacements (it uses standard military issue Uzi parts; mag release button, mag release button pin, mag release button spring, and 2 6/32 stainless set screws you could probably find at any hardware store). Really any original Reising replacement parts are difficult to come by so again this is a significant improvement for anyone that owns a Reising. Again, with wanting to design a durable magwell, I also increased the thickness on the portion that contacts the bottom of the action bar itself. With this, I have also redesigned the taper pins that connect the magwell to the action in the instance that I had to fit the pins to the specific action (ALL Reisings vary slightly in tolerances so this was another hurdle that I had to overcome). On that note;Thank you to all of the members here that provided me with dimensional feedback from their own Reisings!!! The pins that attach the magwell to the action are also precision CNC machined and made out of 300 series stainless. All together, this magwell is about 3x the weight of the original factory magwell (~13.5oz vs ~4.7oz), the added weight under the action does add to enhanced recoil mitigation which is another positive in itself.
Here is a video of it being demonstrated (sorry it's just semi - my range doesn't allow for FA fire)
From all of my testing I have NOT HAD A SINGLE MALFUNCTION! That includes with the action feeding or extracting and with the actual magazines themselves. Other Reising owners that have used these have reported similar results back to me (once tuned to their specific gun). And in some cases even make the gun run MORE reliably.
I do want to reiterate that there may be some minor fitting involved to get the magwell tuned to your specific gun. The most common issue I am seeing so far seems to be with the newer ProMag Uzi magazines having feedlips that are not as wide as the older magazines that they produced. This is an easy fix that only takes a minute to slightly bend them outwards so they are wider, this lets the bolt strip off the round easier to feed. Once this is done performance should be flawless. I recommend running some of the dummy rounds to make sure the magwell is compatible with your specific action before altering your stock. I will try to update this paragraph with any potential issues as I gather feedback from other users. If you have any questions or are interested in learning more about these magwells, my inbox is open.
Thanks for looking and I hope you enjoyed seeing my project - I spent a lot of time bringing it to reality. Stay tuned, I plan on continuing to develop and produce other exciting upgrades for the Reising in the future.
