Enhanced Capacity and Compatibility:
The Tyrant CNC Magazine Extension is designed to increase the ammunition capacity of Springfield Armory Echelon's 15 and 17-round magazines by an additional 5 rounds of 9mm.
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. 
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.
Innovative Installation Technology:
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.
'NoBak' Plunger Technology for Enhanced Security:
The proprietary 'NoBak' plunger technology is a critical component, ensuring our Springfield Echelon base pad/magazine extension remains securely attached, even when subjected to drops from heights exceeding 10 feet with a fully loaded magazine.
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.
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.
