Dangerous? Wow overreacting much?
No, not at all. You may think the risk is acceptable, but not everyone is as smart as you.
Think of a car. Its been sitting in a barn for 20 years. Metal can rust, become pitted, and yes, even stainless steel can. Gun and cars are both made with metal, and require lubrication. I myself, not as smart as you, oh great one, wouldn't trust that everything is ok, and without being able to bore scope it, and take the rifle apart to inspect everything, probably with a reputable gun smith, yeah, I am taking a risk on it, so I am not going to offer top dollar on it. You, in your infinite wisdom might. I don't know. But you certainly make a lot of assumptions, and don't seem to take safety very seriously for someone "military trained". You rely on that excuse a lot, but we all know people that were #### in the military, you might be one of them. I don't know you except from your online persona here, and the same goes for you regarding me. so stop being an ass hat and giving bad advice.
So yes, I stand by my original assessment. I can't thoroughly verify the condition, and all the OP tells us is that its been sitting for 20 years. The risk involved diminishes the value. You don't agree with me, and that's fine, but quit trying to start ####. I get you like to be dramatic and start drama, I see that in a lot of your posts, and this isn't the first time you have tried to come after me, but if anyone is being dramatic here, it's you.
