Description
The Shield Arms Echelon +5 extension is a straightforward way to get more rounds downrange without overcomplicating things. Start with your factory Echelon magazine and add five clean rounds, bringing you up to 22 total. You won't need to swap springs, and the installation takes just minutes with basic tools.
Built to Last with Practical Design
Machined from billet 6061 aluminum and finished with Type II anodized black coating, this extension can handle whatever you throw at it. The material is lightweight but rigid, which matters when you're relying on your gear at the range or in competition. The anodized finish resists corrosion and maintains its appearance through regular use. Index cuts are machined into the body to give you better grip when pulling the magazine from a pouch, a small detail that makes a real difference during fast reloads.
Easy Access Floor Plate for Field Maintenance
One of the best features here is the easy-access floor plate design. You can service or clean the magazine body without removing the extension, which saves time and hassle. This means you can quickly access the spring and follower if needed, keeping your magazines running smoothly without any disassembly headaches.
Competition-Ready and Made Right
This extension is USPSA compliant at the 141.25mm overall length specification, so you can run it in competition events. The whole thing is proudly made in the USA and comes backed by Shield Arms' 100% lifetime warranty, which covers defects and gives you real peace of mind. Works with OEM Springfield Echelon magazines only.
