Overview
The FN America 16" 5.56 NATO M-LOK Midlength Complete Upper is designed for AR-15 builds and features a 16-inch barrel that strikes a balance between maneuverability and ballistic performance. The mid-length gas system enhances reliability and reduces recoil, while the 1:7 twist rate stabilizes a range of bullet weights, making it versatile for various shooting applications. This upper is commonly found in builds aimed at tactical use or general-purpose shooting, where both precision and handling are important.
