New production USA-made Metric followers for the FAL 20-round magazine ( these will clearly be stamped FA-USA). These are treated with a Nitrex process which makes them extremely hard and slippery. Note: When assembling the spring on this follower, you made need the aid of a pliers. This is a tight fit and is meant to be tight as we do not want to have the spring disengage from the follower. NOTE: be sure you are re-assembling the spring on the follower correctly (putting them on backwards is common).
