How to get the most from your Crosman.

There is no way for the writers and presenters of this information to know that you are completing the mods in a proper and safe manner, therefore by using the information herein contained, you assume sole liability for any consequences thereafter.

If you are uncomfortable with performing the modifications, or don't have the mechanical skills, there are professional tuners who can do the work for you at a reasonable cost.

The Crosman Airgun Forum is an international forum, therefore the information herein contained may not comply with laws in your respective country. Compliance with laws in your respective country / jurisdiction is the sole responsibility of the end user.

thank you and enjoy the sport we call airgunning!
