Springfield Armory Kuna .40 S&W 6.12" Black 30+1 KN90640B-FSA

Springfield Armory Kuna

The Springfield Armory Kuna is a semi-automatic pistol-caliber carbine chambered in .40 S&W featuring a 6.12 inch cold hammer-forged Melonite barrel, black hardcoat anodized receiver, and 30+1 capacity. Designed as a compact PDW platform, it includes a multi-port muzzle brake, M-LOK handguard, Picatinny rail, and Strike Industries FSA pistol brace for enhanced control and stability.

The gas-operated system with flat-face trigger delivers smooth, consistent cycling and accurate shot placement. The ambidextrous safety, AR-style grip, and low bore axis reduce muzzle rise for faster follow-up shots. The included FSA brace provides additional support, while the threaded barrel and rail system allow for extensive customization with optics and accessories.

Ideal for personal defense, home protection, and range training, this Kuna offers the power of .40 S&W in a controllable, brace-equipped package. Its compact size, high capacity, and reliable performance make it a versatile choice for shooters who value both portability and stopping power in a modern PDW configuration.
