  1. Can anyone explain the proper procedure for installing the thin barrel nut retaining washer and getting it properly aligned and getting the tabs peened to properly lock the barrel retaining nut. Is there any specific tightness the retaining nut should be tightened to or is basically as tight as possible (within reason)? Does it matter which way that thin washer faces?

    Any help would be greatly appreciated as I don't want to damage anything since all the numbers are matching. Very odd that it is missing to begin with.

    Thanks

  2. Rekraps... that pin must really be in there tight if you can't knock it out. I wonder if it is tapered and needs to be removed only in one direction. I agree that it really isn't worth it unless that buffer spring really feels shot. I'd rather not remove an original pin for no sure reason. A new main recoil spring should be more than enough to keep the wear to a minimum. My recoil spring has a very slight kink/twist to it which is why I want to replace it. I'll probably order a spare butter spring just to have in case of an emergency since Wolff has them and it is only $4

    Strange Ranger... I think the reason they went with a telescoping recoil assembly is that now that they were making stamped receivers they didn't want any risk of springs binding. The old milled receivers like the MP18, Lancaster and Beretta were more robust and conducive for a larger heavier spring. I certainly am not going to ever argue the overly complex German designs and it amazes me the simplicity and dependability of the MP18 and how that jumped to the MP40.

  3. No worries at all. I’m so thankful for the time and help! Thanks so much for confirming things and the great pictures. I think I’ll just swap out the recoil spring and leave the buffer spring alone. A new Wolff recoil spring should be more than enough to help reduce wear and tear. Replacing the buffer spring would have been great but it isn’t worth messing with the original staked firing pin. 
     

    Thanks again!

  4. I don't think my buffer spring needs replacement per say but I picked up a spare complete recoil assembly so I don't risk breaking the original matching numbered part and I figure on my spare I may as well replace the springs with Wolff springs since it will be my shooter recoil assembly and I may as well have brand new springs to reduce overall wear on the rest of the gun.

  5. So in order to remove the buffer and replace the buffer spring you need to remove the pin holding the firing pin in place correct and remove the firing pin? Then the buffer spring tube (47) slides through the firing pin retaining nut (46) and the firing pin is reinstalled. Basically in the end the buffer spring assembly becomes a single unit with the firing pin and firing pin retainer nut.

    I really don't want to remove the firing pin if at all possible since it is staked in place.

  6. So I want to get one of the repro IO MP18 bolts but the only thing holding me back is that the charging handle is sold separately and needs to be press fit into the bolt body. Sadly they said they are so busy they can’t do it for me and I’m not sure really how I’d go about fitting it as I don’t really have any equipment for press fitting. Anyone have any ideas on how I might do it without buggering it up?

    Thanks
