That rifle would have been manufactured between 1983 and 1986, given the serial number.
I found something that sounds similar on Gunbroker:

I have the same question as Decomp, though - are you buying or selling? If selling, I think you're pricing it awfully low, but I haven't seen it. If buying, I'd take it in a heartbeat.

What is the point of rules that are not enforced?
