The KI-9 Upper and Lower sets are now available. They come in five Cerakote color options: Black, FDE, Gun Metal, OD Green, and Burnt Bronze. These sets are made from 6061 Billet Aluminum, which provides a solid and lightweight construction. The completed weight is approximately 1lb 2.3oz.

Some notable features include an integral winter trigger-guard for added strength, a flared magwell for improved magazine changes, and a threaded bolt catch. The upper also has an upper tensioning screw and a bolt catch assembly screw, eliminating the need for roll pins during assembly.

The set includes an ambidextrous bolt release and necessary hardware. It comes with a lifetime warranty against manufacturing defects, providing peace of mind. Additionally, the threaded rear takedown pin detent hole, “Fire” and “Safe” engravings on both sides, and compatibility with Glock magazines make this a versatile option for AR enthusiasts.
