Tuning Cleaning and Lubing a Benjamin Akela 22

Howdy folks! GPeach here back with another burning question.

I am really enjoying my new Akela 22. Some really amazing shots. Squirrels and chippies are in for a big surprise when they hop into my yard!
Anyone ever hear a squirrel scream!? Oh my!
I shot one the other day and he rolled down the hill and when he stopped.....BAM! A red shouldered hawk pounced on it and then flew away with his easy meal. I was shocked but, amazed! It was really cool! Anyway, that's not my question.
In the "owner's manual" there are zero instructions on how to clean the barrel. Ummm. Isn't that part of maintenance? I have looked high and low on the internet and zilch for my gun.
Also, the instructions say to lubricate the O-ring at the breech. What the heck does that even mean? I did order some of the lubricant that they recommended. But, I have no clue as to where to put it or how much to use.
Would one of you kind gentlemen be able to give me some clear instruction here, please?
Thank you so much and have a nice day! ;-)
 
get you some silicone oil like losi 30w shock fluid ... soak a patch and run it through a couple three strokes, then dry patch it a couple 3.times .. thats about it, careful not to run patches too tight and drag a rod on your muzzle crown, so as you were silicon cleaning your barrel you lubed the breech oring, you can also reach in the breech end with a qtip and oil the seal its right there in the hole of the loading end of the barrel ... if you want its a good idea to unscrew the shroud and swab down the inside and barrel itself with the silicone oil, you can use the same patch and be generous with the application .. silicone isnt a long lasting corrosion preventive or lube but it does protect. .. and it wont hurt anything, but i would avoid touching the stock with ii, it may discolor it or cause future issues if you want to refinish it ...
 
@GPeach I have a Benjamin Bulldog and clean my barrel with Ballistol oil, the plastic cleaning rod that it came with, as well as the soft cleaning tips (that screw onto the end of the plastic rod) that came with the gun. My shot groups look good after cleaning and I haven’t noticed any issues. Silicone oil for o-rings or silicone grease (Trident brand) works for me on the breech o-ring as @dizzums mentioned. I also use Ballistol on a rag to wipe down the outside of the rifle. 
 
You can use a soda straw cut to length to put in the end of the barrel so the patch worm or whatever similar you’re using doesn’t hang up in the baffles as you are feeding it into the end of the barrel . I also pulled the baffles out of mine because they were dripping with oil from the factory.I wiped them off and put them back in. My barrel was pretty dirty too when I got it. And for the Q-tip just bend the end of it at a 90° angle and put a few drops of silicone oil and the O-ring will be in there just a little bit at the breech .
 
I like to use a .22 cal bore-snake cleaning rope. I take the outer shroud off completely, then simply feed the weighted end of the bore-snake through the breech end of the barrel, and then just pull the whole thing through slowly so that it doesn’t bind as it makes the sharp bend as it passes through the magazine well into the breech. Two passes usually does the job. Don’t have to worry about damaging the barrel crown this way, and no rods actually get pushed into the barrel. Benefit of this method is that the small brass brush bristles in the middle of the bore-snake ensure you get a good barrel-safe cleaning of the lands & grooves.

Another method I’ve used is to get .22 cal cleaning pellets & load 6 of them into the gun in this order: 3 clean pellets, 3 pellets soaked with a suitable cleaning fluid/lubricant, 3 more clean/dry pellets. Then just take the gun outside and shoot out the pellets in a safe direction, with the end cap & baffles removed from the shroud, because I don’t know if the cleaning pellets would pass through them “cleanly”.
