***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 hardened steel and later nitrided 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 made of stamped sheet metal and then just blued 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. The magazine release parts are much more robust over the originals and much easier to source if you ever wanted to find spares. The magazine release button parts are standard military-issued (Uzi buttons, springs, and pin [if you can't find a standard Uzi pin you can just substitute with a simple 3mm dia x 24mm length pin]). The set screws are just 6/32 threaded and 5/16" in length. I kept the fact that Reising parts are next to impossible to source (and expensive if you do) at the forefront of the project. So if you ever wanted to stock up on spare parts it will be much much easier to do with this magwell.
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 generally without modification (you may need to slightly adjust the feedlips which takes a minute with a pair of pliers - I did not have to with my particular gun) 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.
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). 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 (~12oz 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)
Here's a video of a member running a few magazines through his new gen 1 magwell on FA!
I am happy to report that 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. If you have a question about this please ask and I can provide guidance (it only takes a minute to adjust them). 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.
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. On that note;Thank you to all of the members here that provided me with dimensional feedback from their own Reisings!!!
