I purchased a Crosman Optimus .177 a while back and so has very few shots through it at the moment. I am changing over to the GTX Gen. II trigger and so right now the rifle is all apart.

What else should I do right now to make things smoother, improve function, etc. I thought I read somewhere about polishing the inside of the air cylinder or something? The air bleed is also on its way to being tapped and plugged. I don't plan on putting in a stronger spring. Does it all need to be degreased and then re-oiled? Would pneumatic tool oil be correct? I have lots of that on hand.

Thanks for any thoughts.

NO oil

Clean and dry
Moly grease just behind the seal lip and on rear of piston
Grease spring with a wee bit of the stickiest grease you can find.
Reassemble and enjoy

Moly grease, you mean the black stuff?

For some reason I was thinking of Lithium grease.

lithium grease is too thin,

You may also want to polish the ends of the spring..get them really smooth and shiny then apply the moly. It may seem silly but that allows the spring to rotate freely and not dig into the pieces it is in contact with. Also lube the barrel pivot washers and keep an eye on them by checking for side to side play in the barrel....they are plastic and when they start to wear you can either make shims by cutting up a pop/beer can, or replace them with brass that wont wear.

You are really going to like the new trigger!

Thanks for all the tips. So, no oil whatsoever, just the moly grease?

Dumb question maybe, but how do I apply the grease - behind the seal directly on the piston, or do I put it on the inside of the cylinder? No, then the seal will push it all forward.

You apply the moly to the side of the seal as it tapers down to the piston, and as mentioned above, smear some around the bottom of the piston. Try to keep the face of the seal free of moly...wipe off any on the face. As you cock the gun the some of the moly you applied will get onto the compression tube wall...it really does not take much to keep things moving freely. You may notice a funny smell when first shooting...that is caused by dieseling...it will go away after a while. It does not take a lot of moly...sparingly is best.
