Keith sorry but you have no clue. Nothing rubber on the bolt of any of the three M1's I have and shoot. Beretta's in Argentina? well that would really depend on the outfit. I have seen more Beretta's used in Mexico then I have in Argentina. Both are great guns with +/-'s. You make me wonder how I ever made AA class in sporting clays shooting a Benelli M1. I have over 50,000 rounds thru one of mine and the only jams I have ever had was from very light loads that failed to eject.
