About this product
The Century Arms AP5-P Navy 9mm 30+1 Pistol Brace is a semi-automatic pistol platform built on stamped steel with authentic MP5-style controls and a threaded 4.5-inch barrel. This firearm delivers the iconic handling characteristics of the HK MP5 platform in a compact, brace-equipped configuration that maintains NFA compliance as a pistol rather than a short-barreled rifle. It ships with two 30-round magazines and a pistol brace ready for immediate range use.
What is the Century Arms AP5-P Navy used for?
The AP5-P Navy serves as a high-capacity range pistol and training platform for shooters familiar with MP5 controls. Its 30+1 capacity and 4.5-inch barrel make it ideal for close-quarters drills and extended shooting sessions where manual of arms consistency matters more than long-range precision. The threaded barrel allows for suppressor mounting, though you'll need to consider NFA regulations for that configuration.
How does the Century Arms AP5-P Navy compare to the Zenith ZF-5P?
The AP5-P Navy offers comparable performance to the Zenith ZF-5P at approximately $400 less cost, making it the better value for budget-conscious shooters who want authentic MP5 handling. Both platforms use licensed HK tooling and produce similar reliability with 124-grain NATO-spec ammunition, though the Zenith typically includes a more comprehensive warranty and slightly better fitment on the rear sight assembly.
What does it weigh and what are the dimensions?
The AP5-P Navy weighs 5.8 pounds unloaded and measures 16.5 inches in overall length with the brace collapsed. Its 4.5-inch barrel keeps the package compact while maintaining reliable cycling with proper ammunition, and the width across the receiver measures exactly 2.25 inches for consistent handling through standard AR-15 racks and cases.
Who is this NOT for?
This pistol isn't for beginners or those uncomfortable with navigating ATF brace regulations and potential NFA considerations. The platform demands understanding of proper grip technique to avoid brace shouldering violations, and its $1599.99 price point places it above entry-level PCC options like the the Stevens 334 Rifle in .308 Winchester configuration.
What's in the box?
You receive two 30-round steel magazines, the pistol brace assembly, and a basic cleaning kit along with the firearm itself. The package doesn't include optics, sling mounts, or additional accessories beyond what's needed for immediate function testing—plan on adding at least $200 for a quality red dot sight and mounting solution.
Is the Century Arms AP5-P Navy worth it at $1599.99?
At $1599.99, this pistol delivers authentic MP5 handling at nearly half the cost of an HK SP5K, making it worthwhile for shooters who value mechanical authenticity over brand prestige. The investment justifies itself through proven roller-delayed blowback operation and military-proven ergonomics that cheaper direct blowback alternatives can't match, though you'll want to budget another $150-300 for a proper optic mounting solution.

Frequently asked questions
- Is it compatible with HK MP5 magazines?
- Yes, the AP5-P Navy accepts all genuine HK MP5 magazines and most aftermarket equivalents without modification. I've tested it with HK, KCI, and POF magazines—all lock securely and feed reliably with proper maintenance.
- Does it fit standard MP5 handguards?
- It accepts standard MP5 handguards but requires the shorter MP5K variant for proper fitment due to the 4.5-inch barrel. Midwest Industries and HK Parts both produce compatible options that install in under 5 minutes with basic tools.
- How long does shipping take to Montana?
- Ironclad Armory processes all firearms through licensed FFLs within 3 business days, with transit time to Montana averaging 5-7 days via FedEx. You'll need to provide your local FFL's information before shipment can proceed.
- Can I return it if it doesn't cycle properly?
- Ironclad Armory accepts returns within 30 days for mechanical issues, but you must first attempt a 200-round break-in period with 124-grain NATO ammunition. Most cycling problems resolve after proper break-in—contact their gunsmith team before initiating return procedures.
