Hey guys, First time on this section. My father in law passed away a awhile back, but I have his older Brownin a5. Its well used, but I took it dove hunting opening day, and shot 75 rounds without a hitch. From looking at the gunk in the receiver, I'm not sure it has been taken apart in years. Anyway, I've taken it apart, but I can't seem to get the pin out of the bolt. I know you use a 3/32" punch to tap the pin out. Its to the point I'm worried I am going to damage something. I've been spraying penetrating oil on it. Any suggestions?
