Who is the manufacture of this BB gun.
I assume that you are asking about a .177 caliber BB gun not the toy 6mm plastic BB gun. You didn't state the model of the CROSMAN BB gun. If it's still in production you can get the parts from Crosman.com If it's out of production I suggest that you look on the web under Airgun repair and find a shop close to you to do the repairs.
Follow the maker's instructions on cleaning and lubricating your BB gun, and you will get the most that it was designed to do. If you start changing things in your BB gun, it will put more stress on parts than they were designed to take, and you will break it.
Check with stores that sell BB guns.
If its a BB Gun, Then Yes.
