I picked up a used FN FS2000 today at 400 J&L. Derek gave me a nice deal on it. The guy who traded it in said he shot less than 100 rounds through it, and the wear on the parts isn't much at all.
However, whoever traded it in NEVER cleaned it, and since the serial number is low, it must have sat around in a safe for a long time. It had a good bit of copper fouling on the gas piston and breech( piston looked like the Statue of Liberty), and the gun was dirtier than a $5 hooker inside. I spent two hours meticulously cleaning it from top to bottom and now it looks like new.
If you were the one who traded it in, Thanks for the great gun... However, you suck at cleaning your guns!
Derek, as always, you are the man, and thanks for the great service today even though your were swamped with customers.
