Assembled from high-quality components, the M13 KeyMod hybrid upper is chambered in 5.56 with a 1 in 8″ twist and utilizes a Mid-length gas system for smooth shooting.   The ergonomic 13″ slim, hybrid KeyMod rail free-floats the barrel for accuracy.  Features 4 QD point options for mounting a sling loop, and built-in rail sections at the 3, 6, and 9 positions located at the end of the handguard, where they are most needed.   Keymod slots are available to allow for other accessories if preferred. The 4150 steel barrel is melonite treated for accuracy and durability and is finished off with an A2-style muzzle device.   Carpenter 158 bolt is tested.  Optics ready.
