This is an interesting question. I used to go up on Beemans web page and check out the new air rifles. About 2 years ago I noticed that the Beeman web page is down (You can't access it.)
I know they moved the company a few years ago to Santa Fe Springs. After that it has become hard to find them on the net. However Beeman owns the "Marksman" brand of cheap/low powered air guns, and if you go up on the Marksman web page you will find the Beeman information you are looking for.
Beeman used to be known for excellent quality air rifles ( they use Marksman as a low quality inexpensive air gun to balance out sales of expensive Beeman rifles.) however in my opinion and several others, The quality is falling off with more of their products being made in China.
I find it unusual that they no longer have a web page up, Considering they were a major player in the air gun industry.
I suggest you contact Beeman directly and ask your question: they make several different models. Beeman Co 10652 Bloomfield Ave Santa Fe Springs, CA 90670 Ph: 562-968-5891
I would start with Beeman air gun co. They own the Marksman line of air guns (See the link below) or go online and look up "air gun repair" and locate someone near you to repair the rifle. Or see the link #2 below.
I think you mean CROSMAN not GROSMAN. To contact Crosman simply go to there home page and click on "Contact Us" at the bottom. See the link below.
RWS is currently distributed by UMAREX Co. I would contact them at the link below and ask for assistance.
Your best bet is to contact Daisy air gun co and ask for a diagram. See the link below.
