KP2 pump stroke

I recently aquired a KP2. The pump stroke on it is very hard. What is the best method to loosen it up a bit?
I am very unmachinacal so looking for something simple if possible.

The bolt is probably gummed up and the o-rings may be swollen.
Assuming this is a stock Sheridan KP2
Remove the body from the stock
Roll the bolt until the bolt lug comes up into the slot on the barrel.
Remove the lug with a small screw driver
Pull the pump handle back until the bolt comes out of the barrel.
Do that over a towel to catch the bolt detent BBs that may fall out of the bolt as it retracts
Unscrew the bolt from the pump arm.
Clean bolt.
Clean barrel
Replace o-rings with Danco No. 9 o-rings if required
Lubricate bolt
Slide bolt into the barrel to check for binding. There may be damage to the bolt or corrosion build-up.
The bolt should slide smoothly in and out.
