Bought a muzzle brake at the gun show. The kind where you tap out the pin on the front sight, push brake over muzzle; insert new pin. So I put WD-40-like-substance on pin, let sit for a few hours. Bought a new "Popular Mechanics" punch set from Wal-Mart. Took the 1/16" punch. After about 3 taps with a standard-sized hammer, the 1/16" punch snaps off at the base where it thickens. Yell and scream and curse. Then I hammer on that dang ol' pin with anything else I can find - It ain't budging! So how does one get that dal-blamed pin out? Thanks.
