The small screw in front of the trigger guard will typically be a wood screw on a 541S from the factory. The modification is to drill through the stock where the factory wood screw is and a hole is drilled and tapped into the receiver. A 700 ADL screw that is typically 8-36, takes the wood screws place, and is fitted. The guard is also redrilled and recessed to take the larger #8 screw. The new “second screw” addition doesn’t have to be an 8-36 ADL screw. It can be an 8-24, or 8-32, that is the correct length. An 8 sized screw is typically used because there’s not much room on the receiver for a larger one.
