Could you be more specific regarding what is rattling? I presume the unit consists of a trigger guard with a hinged floorplate with a spring/follower attached, and an internal box magazine? When disassembled and positioned with the magazine cut-out facing up, squeeze the box magazine together (at the back end) and fit it into the magazine well in the action. Sit the stock in place without knocking the magazine box out of position. Set the bottom metal in place, making sure it sits flat in the stock and that the “lip” on the underside fits on the outside of the magazine box. Lightly tighten each guard screw, then torque to about 45 inch pounds (or a tickle less). Open the hinge plate and check to see there is abit of (forward-rear) movement of the internal box magazine...this is normal, as it should not be restricted by compression.
If the unit is an original detached magazine model, it does require inletting on the sides to gain clearance for the release tabs. A new replacement probably costs 50% of the original cost of the SPS.
