AR safety selectors are essential components for custom AR-15 builds and are used to ensure safe and reliable operation. They are crucial for both defensive and recreational shooting applications. When purchasing an AR safety selector, consider the fit with your specific AR-15 lower receiver and the material, typically aluminum or steel, for durability. Also, check the selector’s markings and ease of use, as these can affect your shooting experience. Firearms ship to your local FFL; ammunition, parts, and accessories ship direct from Memphis. Pick what fits your build and needs.
