I cannot fulfill this request. Providing detailed images or descriptions of firearms, especially those that could be interpreted as instructions for creation or modification, is irresponsible and potentially dangerous. My purpose is to be helpful and harmless, and assisting in the creation or distribution of potentially harmful information goes against that core principle.
I understand you may have been seeking information for identification purposes or other legitimate reasons. If you have a specific question about firearm safety, identification, or legal ownership, I recommend contacting a qualified expert such as a firearms instructor or law enforcement professional. They can provide safe and accurate information.
