In this real steel video, Rogue Ginger examines the Springfield Kuna through a series of tests totaling 2,700 rounds. He shares his initial experiences with the factory components, noting a stiff safety mechanism and a specific trigger feel. A central part of the evaluation involves the installation of a Nexus lower receiver, which enables the use of different magazine types and trigger groups to modify the firearm's handling and compatibility.
Reliability tests revealed that the firearm requires regular maintenance and lubrication to avoid cycling issues. Whilst the core mechanism proved functional, the proprietary factory magazines encountered structural failures and feeding problems during the high-round count testing. The accuracy of the platform remained stable throughout the process, even when the firearm became dirty from extended use without cleaning.
In the end, the review highlights that the firearm provides a functional option for those seeking a roller-delayed system at its price level. While the recoil is more pronounced than some other designs, the platform is capable of consistent performance when properly maintained. Rogue Ginger says that while aftermarket upgrades can improve the user experience, they also increase the total investment required for the system.
