First, remove your bolt and check to see if your firing pin is protruding from the bolt when the cocking knob is in the lowered "fired" position.
Also check the stock and see if any of the trigger parts are making any kind of contact with the new stock inletting area around the trigger. This is often a problem, and is normally easily cured by removing a bit of material inside the stock.
Did you change anything on the bolt? Like bolt heads, firing pins, or disassemble the bolt in any way?
