New to Me Chinese Air Rifle

I have purchased a Chinese side lever air rifle from a friend of mine.

I have a few questions on this air rifle. I have furnished some pictures for you viewing pleasure.



  1. Is this a TF-41? Manufacture?
Serial number is K706125. About how old is this rifle?

  1. There is a button on the bottom of the fore stock that seems to move 2 levers in the chamber slightly.
The rifle cocks, fires, and works fine without pressing this button.

Can this button be adjusted to make the levers in the chamber be higher so they catch?

  1. There are 2 holes in the top of the barrel
Is this OEM? I am using the small hole as a stop pin hole for the scope.

Can you oil through the larger hole?

  1. I have oiled all the pivot points. I have put some Pellgunoil on the seal in the chamber.
What else should you oil and how do you get at those spots?

Do you oil the silver sliding chamber sleave?

  1. I see the chamber seal has a nick in it. Is this hard to change out?
Where can you buy parts like this?



I have been using a bent nose tweezer for gently loading the pellet as the larger scope covers part of the loading port. This works well.



I am sure I will have more questions as I move forward using this rifle.

THANK YOU in advance for you answers.

Hello flagger,
How is your chinese machine doing?
I just received one, almost identical, as a gift, and I'm looking for more details on it.
Any tips or details about your experience will be very much appreciated!
Hello,
I still do have mine and shoot it ever so often. I did remove the rear sights as seen in the pictures as my eyes require a scope to be mounted.
I find this rifle to be surprisingly accurate. I tried a few different pellets, and this rifle seems to like the Crosman Domed Ultra Magnum 10.5 GR.
I still have no idea what the button on the bottom of the fore grip is for. See pictures. I think it should have something to do with the bear trap mechanism, but this button does absolutely nothing whether it is depressed or not, and the gun cocks and shoots fine either way.
Does your rifle have this button? Does it do anything?
There is a lot of information on this bear trap mechanism about sticking your fingers in the loading area. Be careful on this. I have never had an issue but never say never. I keep my fingers out of there and load it with a large bent nose tweezers and that works well.
I tried to get some information on a date made but could not find much.
Is yours a side lever cocking like mine?
My wood is in very good condition and the grain is also not too bad.
Could you please post some pictures for us to see? That would be helpful. Maybe that way others may give us some more information on these guns.
ENJOY!!
