Finished this up last night so I thought. Reassembled and now the sear doesn't grab the piston I guess? When cocking the Piston doesn't stay latched
Success!!! The top hat was too long and would hit the rear spring guide while cocking. Now to reassemble and see how bad the spring twang is. I may try a piece of milk jug plastic around the spring or turn a Delrin spring sleeve up.
Okay thanks sorry for the bad drawing its free hand with a mouse but the red dots are the pins and the black is the clip . This is how it should look right ?

Thanks, Ed. You are a big influence on my decision to go with an o-ring and Krytox. I read your posts about o-ring piston seals and Krytox with interest. You have the advantage of access to machine tools I do not have though. I do not use Krytox 105, I use 106. Probably very similar. I get Krytox 106 on my job, it's used in medical devices on bearings that operate under very high heat and pressure. I still use moly paste on spring ends. I have gotten away from using velocity-robbing spring tar. I also like moly paste mixed with Mobil1. I keep both of these lubes away from the piston seal and may we never experience dieseling again!I got a kick out of seeing your o-ring B3 piston. You must've gotten lucky and had a pretty nice compression tube to begin with. The one I have was badly rusted and pitted when new, right out of the box. I honed and polished it until it was oversize but some pits still remain. I used a ARH Tesla seal and gained more than 150 fps over the original synthetic B3 seal.Are you experimenting with dry lubes like molybdenum disulphide or tungsten disulphide?
