In our opinion this is the best looking magazine extension on the market, it has a sharp and simple look.
We decided to do it the right way and made the attachment rail angled, and because of this the extension fits more cartridges than extensions without an angle.
Capacity increase may vary depending on cartridge and magazine, but the standard is 5+.
The extension is easy to install, are as robust as you get it, and has a great finish.
As 99% of our other products this comes with black stainless steel torx screws
