Just got to wondering a while back about these. The white nylon buffers found in some of the early carbines, I include below a couple pics by 101ABN327 from a great previous 607 thread. Does anyone know how they were constructed? I know they were hollow and had weights. But was the front of the buffer a cap glued on? Was the pin in back holding the weight in? How far were they drilled through? Does anyone know of drawings from the original? Anyway. Thanks.

Check this out:
https://www.smallarmsreview.com/archive/pdfdmp_1.cfm?docid=3449.pdf Basically, it's a hollow nylon body; cap and all. There's some kind of small steel cap pinned at the rear and some kind of weight and a hefty looking little spring inside. I'd love to get a better look at one and find out how it's supposed to work. |
My 607 buffer looks "almost" like that one. It's made out of white Delrin with tungsten carbide weights........weighs the same as an H3, but I put an Urethane "bumper" on mine.......just like regular buffers. (wanted modern function with retro look) I could easily take the bumper off, but it can't be seen inside the tube anyways. I've had lots of rounds down the pipe and everything works A-OK

I made one for my 607. I don't have a picture handy of it right now, but it looks exactly like the original in yankee-V's first picture. The insides are the same as Stoner25mkiv's... tungsten weights. In fact he's the one that sent me the weights, when I mentioned to him I couldn't get the buffer as heavy as I wanted with lead. It works great.
I also have a full-length version in my 606 (which is "correct" for that model. It's large enough that I was able to weight it with lead. Believe it or not, you can feel a difference when you shoot the gun, even though it weighs the same as a modern buffer. A picture of it is below. John Thomas

Anything out of delrin would be a breeze to machine.
I made some lightweight ones to play around with on my LW build and cranked out three in about an hr. Don't know what the hell I am doing on a lathe so someone that does would probably take about 5 min. Probably about 30 seconds on a CNC... |

JT, Those look so good I momentarily zoned out on this thread... I am assuming you guys turned your buffers on a metal working lathe. Something I don't have (at least for now). Delrin vs white nylon? Damn, I may have to reconsider making one myself. But I would love to try anyway. Think a wood lathe might work? |

Seems it would be impossible to hold any kind of tolerance. If you do attempt it just remember that you want the buffer to be as HEAVY as can be, yet still allow the action to cycle.....that will, for sure, require added weight to the buffer. Nylon, Delrin or any other plastic, even UHMW is going to be much too light by itself to allow proper operation of the action. |
