I was taught to "wet sand" it with 1000 then 1500 grit sand paper with tung oil. The two upper hand guards came out looking mint. the lower stock looks a 1000% better than it did but theres no hiding its troubled child hood. plus I really gave the barrel a good scub and what I thought looked like pretty good rifling looks more like a threaded hole thats had its threads stripped out of!!!!Yikes!!
