Looks like the baffle part of the bolt is also the bolt stop. I am changing from 223 length case to 308 length case so the bolt hasn't sufficient room to work properly with magazine so I am assuming that I can cut and grind off that part of the baffle the acts as the stop. Anybody with experience here chime in and helpme out as to how much to cut off. I can likely guess right but experience trumps...thanks...Jack
