If you run a Springfield Echelon and want more rounds on tap without permanently altering your magazines, this extension gets the job done. It's built from aerospace-grade T6061 aluminum and precision CNC-machined to match the exact dimensions of your magazines. The bead-blasted finish with hardcoat black anodize handles hard use and looks clean alongside your pistol.
What sets this apart is how simple it is to swap on and off. There are no tools needed and the extension takes seconds to install, which matters if you're switching between configurations or just want to keep things flexible. Inside, you get a 10% power spring that's 110% stronger than the factory spring, meaning that last round still feeds smoothly and your slide locks back reliably after the last shot. That reinforced spring also helps prevent the extension from backing off during hard use.
The solid ledges on the top and bottom of this extension give your fingers something to grab during speed reloads or when you need to pull a stuck magazine out in a hurry. This might sound minor, but it makes a real difference when you're under time pressure at the range or in competition. The extension works with both 15 and 17-round Echelon magazines, but it won't fit the 10-round version.
You're looking at a machined aluminum piece that brings the same fit and finish standards that keep Tyrant CNC accessories in the game. The black anodized finish matches factory Echelon aesthetics and resists corrosion. This is a lifetime warranty product from a manufacturer that's been doing precision machining for decades.
It fits the 15 and 17-round Echelon magazines, but does not work with 10-round magazines. Make sure you have one of the compatible sizes before ordering. If you're not sure which magazine you have, check the witness holes on the side of the magazine to count the rounds.
No, the whole install process is tool-free. You just slide it onto the magazine baseplate and it locks in place with the spring-loaded plunger system. Takes seconds and you can remove it just as quickly if needed.
The spring included with this extension is 10% stronger than the original factory spring and has an extra coil. This extra power ensures that every round feeds smoothly all the way through your magazine, including that final round, and maintains slide lock-back when the magazine is empty.
Most setups work fine, but some aftermarket grips with integrated magwells like the Icarus Precision ACE magwell can interfere. If you're running custom grips or magwells, verify compatibility before ordering to avoid fitment issues.
