John I'm so glad to hear your reply. I sourced some my replacements from you so I'm glad you responded. The recoil guide rod I received with the gun appears to me to have been damaged. I have two replacements to compare it to, One from you and one from numeric. Here are a few pictures that show you what I'm talking about. 1. Comparing the damaged recoil assembly on the right (notice that the legs are spread out), vs the one from you, legs curved in. I suspect that this is due to it slowly pounding the recoil assembly wider over time. Which I believe might eventually serve to spread out the rear receiver pieces. https://imgur.com/f0MmCPE 2. Here you can see the recoil assembly you sent me with a rear buffer installed, Notice it's flat back edge, which is contrast the buffers you observed, which were round. This is one I made but mirrors the one I found in the recoil assembly I got from numerich. https://imgur.com/CyE51JT 3. Lastly here is a recoil assembly with both the washer type buffer you sent me, and the original buffer installed. When I ran the gun in this configuration a NOTICEABLE increase RPM occurred. https://imgur.com/7tKcO06 It seems likely that based on the recoil guide rods I got from you and numeric that a buffer was original intended, I'm not clear on the rubber washer buffers, but maybe they were to be used in lue of the rear buffer rather than in addition too. When both were installed the RPM went up to 600, and the bolt would sometimes fail to engage the trigger sear. In addition, I took some high speed, It seems to me like the buffers are basically Not really even needed... as the bolt never really comes close to impacting the rear of the weapon and bottoming out. Which makes me wonder if the rubber washer were there to allow you to increase or decrease the rate of the weapon. Do you happen to know the source of the 1100 kits you sourced back in the day? Here is some slow mo of the weapon in action... you can see the bolt doesn't come close to impacting the rear of the receiver. https://imgur.com/vBbClEY

I'm leaving this here incase anyone in the future finds this. I was able to source a new old stock guide rod assembly that does infact have the rubber pad on it. I'm going to cad one up and print some replacements out of flex filament.

Hey guys, I just picked up my first machine gun, a madsen m50, I've very pleased with my purchase and the gun runs fantastic. When I was taking it apart to clean it I noticed, that the recoil guide rod is missing the rubber bumper the back end. When I bought the gun, the seller had his own, and his was missing it as well. Is this something that just rots out over the 70+ years of the guns existence, or did not all of them have it? Does anyone make replacements? Thanks in advance.

Thanks buddy. Got a hold of John on the phone. I think we will be able to work something out. ~N0mad

Thanks, Charlie. Looks like he used to have a hand in the dealershowroom which is now defunct. I can't find any further contact info on him.

Looking for a Madsen M50 parts kit. Let me know what you have and what you want for it. Thanks guys!
