| I have an older SP1 with an edgewater buffer. The cap, for lack of a more correct nomenclature, moves freely for about half of its travel, then it has high resistance. Is this an indication that the spring disks/rings are jammed up? And if so, how would one disassemble the buffer? Roll pin thst holds cap is accessible from one side only. Thanks for any help. |

If you shake it and it rattles, and the cap moves the way you explain, you should be good to go. |

That's how it's supposed to be. There's no spring tension; the cap and spring stack move freely on the buffer body. They're purely there to absorb impact. That's why you get such high resistance when you push on them. It's like one of those plastic recoil buffers only, it's made of metal.
If you want to take it apart, tap the roll pin into the buffer body. It's hollow so the roll pin will just fall inside of it and you'll be able to get it when you take the buffer apart. DO NOT use oil or any kind of wet lubricant on any of the inside parts. That WILL cause them to bind up. Dry lube only. Some kind of spray on molybdenum is what the original is I believe. And no graphite. |
