I am satisfied with this purchase. I have not had problems other reviews had about the trigger moving or turning. My wheeler electronic trigger scale says it is set at 5 oz. Very pleased. No safety or bolt release. I don't run the bolt lock lever ....the cheek weld on my stock keeps the bolt from coming all the way out. I would recommend this trigger to a friend and would consider buying another. This is used on a bench gun. Don't hunt with it probably to light of pull for a hunting rifle. You might fire the round before you mean to.
