Entire product lines of firearm magazines have been built based on their reputation for reliability and performance. Stress Outdoor® recognizes that a fundamental understanding of the product requirements is essential to the development of a five-star magazine; this in-depth knowledge ensures that designs meet or exceed design requirements and separates high-quality brands from the rest. Whether it’s in the design of military rotary cannons and their supporting ammunition delivery systems resulting in thousands of rounds per minute of firepower or the requirements of a pistol magazine repeatedly delivering a cartridge without jamming, Stress Outdoor® understands the dynamics and mechanisms involved in both good and poor performance.
