MAGAZINE EXTENSION FOR SPRINGFIELD ARMORY ECHELON The Tyrant CNC Magazine Extension, or also known as base pads, are expertly designed to increase the ammunition capacity of Springfield Armory Echelon's 15 and 17-round magazines by an additional 5 rounds of 9mm. This enhancement is crucial for users seeking increased capacity without compromising the firearm's reliability and performance. Precision Engineering and Materials: Each Springfield Armory Echelon magazine extension is CNC machined from T6061 aerospace-grade aluminum, a material chosen for its optimal balance of strength and lightweight properties. This level of precision in machining ensures a perfect fit and function with the Springfield Echelon models. Durable and Aesthetic Finish: The finishing process involves bead blasting followed by a hardcoat anodize, providing not only a durable surface resistant to wear and tear but also an aesthetic appeal. This finish is consistent with the high-quality standards set by Tyrant CNC and complements the overall look of the firearm. Innovative Installation Technology: A standout feature of the Echelon magazine extension is its tool-less installation and removal capability, a significant advancement over other market options that often require tools and are prone to disassembly upon impact. This design aspect emphasizes ease of use and maintenance, appealing to a wide range of users. 'NoBak' Plunger Technology for Enhanced Security: The proprietary 'NoBak' plunger technology is a critical component, ensuring the Springfield Echelon base pad/magazine extension remains securely attached, even when subjected to drops from heights exceeding 10 feet with a fully loaded magazine. This feature provides users with confidence in the product's reliability under various conditions. Optimized Spring Design for Reliable Performance: Accompanied by a 10% power spring (110% stronger than OEM with an additional coil), this Springfield Echelon magazine extension is engineered to guarantee the consistent delivery of the final round and maintain slide hold-back after the last round is fired. This attention to detail in spring design enhances the overall functionality of the firearm. Purposeful Aesthetics for Practical Use: Tyrant CNC base pads are not only designed for increased capacity and reliability but also for practical handling. The solid top and bottom ledges facilitate quick and efficient magazine changes, beneficial in fast-paced situations or when handling is compromised. This feature also aids in the removal of stuck magazines, showcasing the product's user-centric design. Cohesive Design with the Tyrant CNC Product Line: In line with the Tyrant CNC's commitment to quality and aesthetics, the magazine extension's design harmonizes with the rest of the Tyrant CNC line for the Springfield Armory Echelon. This consistency ensures that users can give their firearms a cohesive and customized appearance without sacrificing functionality.
