timkel Posted June 4, 2017 Report Share Posted June 4, 2017 Don't remember where or when I got these. But they might look familiar to some. They came in a package of three. Kept them in my spare parts box. Took them out of the bag today and they crumbled into pieces. upload pictures Link to comment Share on other sites More sharing options...
dalbert Posted June 4, 2017 Report Share Posted June 4, 2017 I've had the same thing happen with some old M1911 buffers. They must have a fairly short shelf life, but had likely been in my spare parts for 20+ years. I have no idea where I got them, back in the day...

Motorcar Posted June 5, 2017 Report Share Posted June 5, 2017 Sorry no picture, my antique flip phone stopped sending photos years ago. The ones I got from him are a black neoprene/urethane(?). I got a couple years ago from him and they are still look new running thousands of rounds, one in a friend's rental 1928. Link to comment Share on other sites More sharing options...
buzz Posted June 6, 2017 Report Share Posted June 6, 2017 the yellow translucent plastic buffers are polyurethane (synthetic resin) the black rubber buffers are neoprene (synthetic rubber) the original red buffers are the original commercial synthetic plastic called bakelite (phenolic resin). The polyurethane and neoprene are a LOT softer than the bakelite The polyurethane is probably the best of the three. We need to see if the buffer ever gets hit by the bolt. Maybe put some scotch tape on the gun at the end of the actuator slot an see how far back the actuator comes. Just keep moving the tape until it just barely clears the actuator travel.

OCM Posted June 6, 2017 Report Share Posted June 6, 2017 (edited) PK buffer- I just emailed PK and he dropped them in a envelope and mailed them. ( need to send payment of course) . Then be done with it. 5, 10 bucks or something, can't remember. Edited June 6, 2017 by OCM Link to comment Share on other sites More sharing options...
timkel Posted June 6, 2017 Author Report Share Posted June 6, 2017 These buffers are sold by Keystone Arms. They are the same size and shape as an original. I do not know what material is used. image hosting over 5mb Link to comment Share on other sites More sharing options...
