happydude, many of us here very seldom get rid of the rifles we buy. We will sometimes sell or trade one if we find a better replacement or maybe in times of financial need. For one thing, milsurps especially, just seem to go up in value. The exception right now seems to be the Mosin Nagants other than the Finnishmodels. The reason for this is the supply of cheap ammo is drying up. The same thing happened to Lee Enfields in the early sixties and seventies. Now, original rifles are makeing the $10 investment that was probably bought to cut down as a sporter look like a real gem.
Sometimes I envy guys like you that get bored with something and just get rid of it. Then I go through the safes and look at some of the stuff bought just for curiosities sake and never fired or even handled much, other than to clean it up and still get a lot of enjoyment out of wondering about the stories they could tell and compareing there virtues if they have any. Then the envy goes away.
I really don't believe that you don't have an extensive collection or get bored with it. Maybe the Chinese SKS you had was one of the earlier commercial models. I still regret tradeing the fibreglass stocked milsurp Chinese SKS that I traded for a couple of Lee Enfields.
