Tyrant Cnc Tdechemagex17Gold Mag Ext 9Mm Springfield Echelon 5Rd Gold Alumn

If you run a Springfield Armory Echelon and want to squeeze more rounds into your carry or range setup without swapping guns, the Tyrant CNC magazine extension for 9mm Echelon mags is a smart upgrade. This gold-anodized aluminum base pad adds 5 rounds of capacity to your existing 15- or 17-round magazines, bringing you closer to the firepower you need for defensive training, competition, or duty carry. The extension installs tool-free, drops on and off as easily as swapping a mag, and uses Tyrant's proven 'NoBak' plunger design to stay put even after hard impacts or fumbles on the range.

Built from T6061 aerospace-grade aluminum and finished with hardcoat anodize over a bead-blasted surface, this extension won't rattle loose or wear out after thousands of cycles. The real engineering detail is under the hood: a 10%-power spring (stiffer than factory) ensures the last round feeds reliably and the slide locks back consistently when the mag runs dry. The solid ledges top and bottom make speed reloads smoother and help you fish out a stuck magazine when things get rough.

This is purpose-built for the Echelon platform—it fits the 15- and 17-round factory mags but not the 10-round single-stack or the 20-round (which is just a 17 with a 3-round OEM pad). Pair it with a quality holster and mag carrier, and you've got a practical bump in capacity without compromise.

Frequently Asked Questions

Which Springfield Echelon magazines does this extension fit?

This extension fits both the 15-round and 17-round Echelon magazines. It does not fit the 10-round single-stack magazine. Note: the 20-round Echelon magazine is a 17-round magazine with an OEM 3-round extension already installed, so this extension is not compatible with it.

Do I need tools to install or remove this magazine extension?

No. The Tyrant CNC extension is designed for tool-free installation and removal, so you can swap it on and off without any armorer's tools or special equipment.

Will this extension stay attached during hard use or if I drop the magazine?

Yes. The 'NoBak' plunger technology is engineered to keep the extension secure even after drops from heights exceeding 10 feet with a fully loaded magazine, so it won't back off under normal carry, training, or duty conditions.

Does this extension work reliably with standard 9mm ammo and slide lock-back?

Yes. The extension uses a 10%-power spring that is 10% stronger than the OEM spring with an additional coil, ensuring reliable feeding of the final round and consistent slide lock-back after the last shot.
