The Springfield Armory Kuna .40 S&W 6.125" FSA M-LOK Pistol delivers a modern, compact pistol-caliber platform built around a roller-delayed operating system for smooth, controllable shooting. Its cold hammer forged, black Melonite 6.125" threaded barrel pairs with a multi-port muzzle brake for consistent accuracy and fast follow-up shots, while the aluminum upper, polymer lower, and full-length Picatinny rail provide a solid foundation for optics and accessories.

This model features integrated flip-up sights, an ambidextrous safety and charging handle, and an AR-pattern grip for familiar ergonomics. The Strike Industries FSA brace offers added stability and an adjustable length of pull, making the Kuna well suited for range use, training, and recreational shooting where compact size and easy handling are priorities. Backed by Springfield Armory’s reputation for thoughtful design and dependable performance, this pistol-caliber platform is built for shooters who value refinement in a compact package.
