Moly 29 right out of the tube (using sparingly) on the outside of the spring.
I inserted rolled paper to try and limit the tar application to the outside as best I could.

Moly Paste was made with a 50/50 mix between the powder and silicone.
MolyLube was made with a 20/80 mix between powder and 20wt.non detergent oil.
To start with the diagram doesnt lend much on disassembly. Fortunately the instructions from Jordan Batchuarov gave his insights to this end. Unlike others (I assume) the end screws off and Jordan suggests making a block to fit. I went one step further and also drilled a hole and used the screw that holds the end through the stock. You can see in the picture but it made it easier as the block would now stay with the end cap both unscrewing and screwing when done.

The trigger came out easily after removing the pin. Reinserting trigger (after tarring spring and cleaning and lubing the piston with paste) was done after application of MolyLube to all points of contact.

The added force of the longer spring proved a little difficult when trying to screw it back together. It didnt help that I got it all together and had to open it back up since I forgot to put the spring guide in the spring the first time.

To finish it all off I MolyLubed all joints and springs located throughout the rifle.
The twang is now gone and it seems to shoot harder.
Hope this helps someone.
