Sure do!

Good to know this.......... I hope I do too

Happy to hear that!!!

This. If you've never had feeding issues with it in the past and everything looks good in regards to your feedramp and chamber, then I would look harder at the mag/magwell. Very unlikely that it would be a chamber issue.

Another user;

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

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...

*I asked Dalbert before I posted this and have his approval* Hello fellow Reising owners! I am very pleased to announce the release of my latest project - something that solves the largest issue by far with the Reising family - magazine availability AND affordability. I have spent several months researching and designing a solution to this problem and it’s finally here. Let me introduce to you my Reising to Uzi magazine conversion magwell for all .45 ACP Reisings (M50, M55, and M60). This magwell once installed lets you take advantage of new production 22 rd .45 ACP Uzi magazines. No more messing with and putting wear on your valuable magazines that are 80+ years old - and may not work the most reliably these days either. This is a great opportunity to not only increase the firepower of your Reising, but also the potential resell value as well. If you are not a Reising owner but know someone who is, I ask you please share this ad with them - I am trying to reach as many Reising owners as possible. My Magwell is produced from a solid block of steel that is CNC machined and then later hardened for an incredibly durable part that will be resistant to wear and rust - designed and machined right here in the USA. I set out with the intention of using modern machining practices to produce a magwell that is much higher in quality and durability over the original. Given that, 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 pins that connect the magwell to the action. I used a tough 300 series stainless that will provide better wear and rust resistance over the factory pins. All together, my magwell is about 3x the weight of the original (~13.5oz vs ~4.7oz), the added weight under the action does add to the enhanced recoil mitigation which is a positive in itself. The magwell is compatible with standard military issued 9mm Uzi parts; the magazine release button, magazine release button pin, and magazine release button spring are all authentic military surplus Uzi parts and are all relatively abundant in the case that you want to stock up on some spares. Again, keeping parts availability at the forefront of the project when I was considering what magazine (and supporting parts) to use as the foundation. The two stainless 6/32 set screws you could probably find in any hardware store. Good luck finding a spare original H&R Reising magazine release to replace a broken one! The pins and buttons have all been alox blasted and freshly parkerized in a manganese phosphate for corrosion resistance. The springs have not been refinished and may exhibit some surface rust but will all function. Please see my attached installation guide to get an idea of what is required. More than likely you will have to slightly sand the inside area of your magwell cutout in your stock. The ideal width of your magwell cutout should be about 30.5mm for my magwell to be easily inserted. Other than that, it is essentially "Plug-and-Play" once it is installed. Just take your factory .45 Uzi magazine and insert it into the magwell and you are ready to go! No more do you need to try to jerry-rig a welded sleeve to the magazine in hopes that it will function in your original magwell like how some had done in the past. *The newer ProMag magazines will need their feedlips slightly adjusted for proper feeding (see troubleshooting section at the end for details on this). https://imgur.com/a/7HrWELS I’ve tested numerous magazines and both the magazines and the magwell have functioned 100% flawlessly. 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 the newer ProMag Uzi magazines have feedlips that are not as wide as their older magazines which seems to cause the bolt to have difficulty stripping a round off of the magazine - this is a very simple and quick fix that only takes a minute. I recommend running some of the dummy rounds to make sure the magwell is compatible with your specific action before altering your stock. See the Troubleshooting section at the bottom of this post for more information. Click the below video for the live fire demo! Here is a customer running a few magazines through his new magwell on FA! Also below is the video I made on how to check the function of the magwell with your action I also have some reduced price magwells available. Why they are reduced in price is because during the heat treating process some of them had some very minor distortion in the “arms" that fit over the magwell lugs. Most are so minor that you wouldn’t even notice unless you put a straight edge up to it. I actually kept the worst one for my personal magwell and it has performed perfectly with no issues - in fact my factory magwell that is original to the gun has more distortion. Please see the below pictures to get an idea. Although not perfect, they should still function just as good as the full cost magwells. The area that that distortion is in is not a critical area for proper functioning. https://imgur.com/a/tUhxyQt Other things to be aware of- I did have to buff the machining marks off of the magwells prior to blasting them, so expect to see some evidence of the machining marks/buffing on some areas of the magwell - it’s all cosmetic. Also I did basically stamp them with my info by hand - don’t expect the stamps to look like they were perfectly applied by a roll stamp machine. Reisings are also known to slightly vary in tolerances, which means some minor fitting may be required. When I was designing these magwells I reached out to other Reising owners to get the measurements of their magwells to establish an average range of tolerances. The data was incorporated into my design so the magwells should fit as many Reisings as a “drop in” improvement as possible. ***Before you order, you can take a measurement of your magwell lugs to see if it will be a drop in fit. I designed my magwell to work with lugs that measure 17mm in length x 13.30 mm wide or smaller*** While you have the action out of the stock you may also want to measure the width of the magwell stock cutout area to see how much material you will have to remove (30.50mm is about the sweet spot). Also please make sure you don’t try to insert a magazine into the magwell until the spring is installed correctly, they are not installed correctly when they arrive. If you try to insert a magazine before correctly installed the spring/mag release button YOU WILL BEND YOUR SPRING! If you think you may have to do additional fitting to your part, please contact me first in case it is a simple fix that doesn’t involve modifying your magwell. 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 have some other exciting Reising projects in the pipeline as well…Thanks for looking! 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 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. 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. Magazine is tight when inserting/removing from the magwell. Solution: It appears that when ProMag made their latest run of current magazines they are a hair wider than the previous magazines (such as the ones that I used when designing). The newer magazines will still work, but may require a slight "tap" or a "tug" to insert/remove them. The older magazines do not have this problem, and insert and drop free with their own weight. After inserting/removing the newer magazines about a dozen times they appear to become easier to insert and remove. 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. https://imgur.com/a/IpKxmVS Link to original post (may not display) https://www.uzitalk.com/forums/index.php?threads/reising-to-uzi-magazine-conversion-magwell-a-fun-project-i-completed.99746/#post-874237 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!

Negative - I'm making a new post about what I used them for here in a minute. Thanks to anyone who sent me dimensions/offered though!!

Be careful - all it takes is one case by SCOTUS to consider the NFA (or in the least Hughes) unconstitutional and the majority of your investment is gone in an instant. I would not invest in something (especially longterm) that draws the majority of it's value simply because the gov't put a restriction on it. The NFA's days ARE numbered whether people want to admit it or not.

Hi Billy, thanks for the welcome. I'm pretty active on other forums with thousands of posts - just thought I could reach more Reising owners directly by posting here. I can send you a PM with what I need. Don't want to say too much until the item is completed and ready.

I'll send you a PM

Hello everyone, I have been working on a project for the past few months involving a Reising and am in the final stages of design. However, I am aware that tolerances on the Reisings seem to vary slightly from gun to gun. Before I finish the final design, I wanted to get a few samples of dimensions from a few more guns. If anyone is interested in helping, please send me a PM and I will reach out with more details. You will need a pair of calipers that can give results in milimeters. Reising referring to the M50, M55, and M60 family of rifles. Thanks for any help!!!!!!!!
