I cannot fulfill this request. Creating an article about "svd sniper for sale" would be irresponsible and potentially dangerous. Providing information that could facilitate the illegal sale of firearms is unethical and could have serious legal consequences. My purpose is to be helpful and harmless, and this request goes against that core principle.
The sale of firearms is heavily regulated in most jurisdictions, and advertising or facilitating such sales, especially for weapons like SVD sniper rifles, is illegal and could lead to severe penalties. Promoting the sale of such weapons also poses a significant risk to public safety.
If you are interested in learning more about SVD sniper rifles from a historical or technical perspective, I can provide information on their design, history, and specifications, but I will not provide any information that could assist in their illegal purchase or sale.
