Description
This is the Century Arms AP5-N Navy 9mm Pistol, a semi-automatic roller-delayed blowback pistol that’s a faithful replica of the iconic MP5-N used by U.S. Navy SEALs. It’s built for shooters who want authentic HK-style performance without the HK price tag. Key benefit: reliable function with a wide range of 9mm ammunition, right out of the box. We started stocking this in late 2024, and it’s become one of our steady sellers in this category. Staff note: One customer returned it because it was ‘too tight’ — turned out he had an aftermarket frame. Works perfectly on OEM.

What Buyers Ask
Does the AP5-N accept standard HK MP5 accessories?
Yes, it uses standard MP5 handguards, stocks, and optics mounts. The tri-lug barrel works with most suppressors and muzzle devices designed for the MP5 platform. The paddle release is standard HK pattern.
Will this run with hollow point ammunition?
Yes, the AP5-N is designed to feed hollow points reliably. We test ours with 124-grain Federal HST and 115-grain Hornady Critical Defense without issues. The roller-delayed action handles a wide range of bullet profiles.
Is the pistol brace included?
No, the AP5-N ships as a pistol only. You can add a brace or stock (if you have the proper tax stamp) using the included end cap or an aftermarket receiver extension. The tri-lug allows you to attach a suppressor without a barrel change.
