Description
The Tyrant CNC magazine extension brings extra capacity to your G19 or G23 without requiring any permanent modifications or tools. Constructed from 6061 aerospace-grade aluminum with a matte black finish, this extension slides onto your magazine base pad in about 10 seconds and comes off just as fast. The included 10% power spring ensures reliable feeding at the increased capacity.
NoBak Retention Plunger Technology
What sets this extension apart is how it installs. Most magazine extensions require disassembly or special tools, but Tyrant's NoBak system uses a simple retention plunger that lets you slide the extension on and off without touching a single tool. Push the plunger down and it releases instantly. This means swapping between standard and extended capacity takes mere seconds, giving you flexibility whether you're training, competing, or carrying.
Weight and Control Benefits
The aluminum construction adds noticeable heft to your magazines, which helps them drop free faster during reloads. The knurled surface and chamfered edges provide a positive grip even under stress, making it easier to strip the magazine from your pouch when you need it. Whether you're in a competition stage or a defensive situation, these details improve your control and reload speed.
Compatibility and Reliability
This extension works with Glock 19, 23, and 26 models across Gen 1 through Gen 6. It's compatible with factory Glock magazines and most aftermarket options, though it doesn't work with PMAGs. Each extension ships with an upgraded power spring that's 10% stronger than the factory spring, engineered specifically to handle the increased round count reliably from the first shot to the last.

Frequently Asked Questions
Will this extension work with Magpul PMAG magazines?
No, this Tyrant CNC extension is not compatible with Magpul PMAGs. It works with factory Glock magazines and most other aftermarket Glock-compatible magazines, but not with Magpul's polymer design. Factory and other aluminum or steel-based aftermarket mags will work without issues.
How long does installation take?
Installation takes about 10 seconds and requires zero tools. The NoBak retention plunger technology lets you simply slide the extension onto your magazine base pad. Removal is just as fast: push the plunger down and slide it off. No disassembly needed.
Does the extension come with a new spring?
Yes, each extension includes an upgraded 10% power spring that's engineered specifically for the increased capacity. This stronger spring ensures reliable feeding from the first round to the last, even with the additional rounds stacked in the magazine.
Will this fit my Glock 26?
Yes. The Glock 26 shares the same lower half geometry as the 19 and 23, so this extension is fully compatible with G26 magazines. It will add the same +5 rounds for 9mm or +4 for .40 caliber as it does for the other models.
