I just spent hours last Wed. breaking in the barrel on my first semiauto rifle, A National Match M1A. It is a whole new world. It was what I always wanted and I am very pleased. Thanks to the folks here I finished the stock properly with tung oil, seasoned the barrel, and damn near cleaned it to death.
