Several here have already discovered that 1911 pistol recoil buffers fit nicely in the Mini-14. Of course, this is at the guide rod (rear) end of the assembly. Some have experimented with a second buffer at the front end too, placed around the gas pipe. I saw MasterPsmith's photo of one that he used at that end, and it resembled the "cooked" experiments I've tried. Does anyone know of a heat-resistant material that also has a cushioning effect? As I stated on another thread, I grew weary of the molten "goo" I was creating, so I haven't tried anything recently. Ideas?
