Drop-in enlarged ambidextrous safety levers for the FN SCAR with a positive, easy-to-find shelf.
The factory FN SCAR safety lever works, but it is small and the shelf is easy to miss with gloves or under stress. PMM's SCAR safety selector levers swap in an enlarged, contoured shelf that your thumb finds without looking. It is a drop-in part that fits the SCAR 16, 17, 20, and 15P, and at $25 it is one of the cheapest meaningful ergonomic upgrades on the platform.
Parker Mountain Machine is the dominant SCAR-specific aftermarket shop, and its lower-receiver parts are the ones SCAR owners reach for first. The selector levers are sold direct from PMM.
