Description
The AP5-P Navy in RAL8000 FDE is Century Arms' ultra-compact take on the legendary "K" pattern MP5 format, and this particular configuration is one of the more desirable variants in the lineup. Manufactured by MKE in Ankara, Turkey using original H&K-spec tooling, the AP5-P is as close to the real lineage as you can get in a semi-auto pistol without paying HK SP5 money. The roller-lock delayed blowback action is what sets this platform apart from the sea of straight blowback 9mm pistols — it runs smoother, produces a softer impulse, and stays flatter on target through fast follow-up shots. At just 13.7" overall and 4.6 lbs, it handles quick and stores compact.
What Makes the AP5-P Navy Configuration Stand Out
The Navy variant is built around the short "K" pattern, which means a condensed handguard with an integrated hand stop, and the ambidextrous Navy-style grip assembly. The stamped steel receiver is finished in FDE Cerakote over manganese phosphate — the RAL8000 designation refers to this specific earth-tone color scheme that gives the gun its distinctive look. The 5.8" cold hammer-forged chrome moly vanadium barrel has a 1:9.8" twist and comes threaded at 1/2×28 with a 3-lug quick-attach adapter, so you have options whether you want a direct-thread suppressor or a tri-lug mount. An adjustable rear diopter drum sight is standard, and the included claw-mount Picatinny rail lets you drop on a red dot without hunting for a mount separately.
Running the AP5-P Navy at the Range
One thing worth knowing before your first range trip: Century's own documentation recommends a break-in period of approximately 500 rounds using factory 124-grain NATO or 9mm +P ammunition, with consistent cleaning and lubrication throughout. Roller-delayed guns can run a little stiff when new, and following that break-in protocol makes a real difference in long-term reliability. Once it's loosened up, the platform is well-regarded for its smooth, soft-shooting character — the kind of thing that makes a full day of range work genuinely enjoyable. The AP5 does not have a last-round bolt hold open, which is true to the original MP5 design, so that's something to be aware of going in. Feed preference leans toward FMJ round-nose ammo, though most standard 9mm should run fine after break-in. Note that +P is acceptable, but the platform is not rated for +P+.

Frequently Asked Questions
What does the "Navy" configuration mean on the AP5-P?
The Navy designation refers to the classic short "K" pattern configuration originally developed for naval special operations units. It features a condensed handguard with a hand stop, an ambidextrous Navy-style grip assembly, and the compact overall profile that defines the K-variant format. On this FDE model, that same layout is finished in RAL8000 Cerakote for a more distinctive look compared to standard black models.
Is the Century Arms AP5-P Navy suppressor compatible?
Yes. The 5.8" barrel comes equipped with both a 3-lug quick-attach adapter and a 1/2×28 threaded muzzle, giving you two options for attaching a suppressor. The roller-delayed blowback operating system is also a natural fit for suppressed shooting, since it delays the bolt opening until chamber pressure drops — which reduces backpressure compared to straight blowback designs. Century recommends completing the 500-round break-in period before adding a suppressor so you can establish a clean reliability baseline first.
Does the AP5-P have a break-in period?
Century Arms officially recommends approximately 500 rounds to break in the roller-delayed system, specifically using factory-new 124-grain NATO or 9mm +P ammunition during that window. Keeping the gun clean and properly lubricated throughout the process is also part of Century's guidance. Roller-delayed actions can run a little tight when new, and going through this process before experimenting with different ammo or accessories gives you the best chance of a smooth long-term experience.
What ammo runs best in the AP5-P?
Century's own FAQ notes that the platform feeds most reliably with full metal jacket round-nose ammunition, which is the classic choice for this type of action. Most standard 9mm loads should work fine after break-in. The AP5-P is rated for standard pressure and +P loads, but is not rated for +P+ ammunition, so stick below that ceiling. Once the break-in is done, the platform handles a wide range of factory 9mm without issues.
Does the AP5-P Navy have a last-round bolt hold open?
No, and that's true to the original design. Like the MP5 it's based on, the AP5-P does not include a last-round bolt hold open feature. When the magazine runs dry, the bolt will ride forward on an empty chamber. You'll reload and use the charging handle to chamber a round — the classic "HK slap" method that MP5 fans are very familiar with.
What is the RAL8000 finish and how durable is it?
RAL8000 refers to the specific earth-tone tan color in the standardized RAL color system, and on this AP5-P it's applied as a Cerakote coating over a manganese phosphate base treatment on the steel receiver and components. Cerakote is a well-established polymer-ceramic firearm finish known for strong corrosion and wear resistance. The combination of phosphate under Cerakote gives the metal surfaces solid protection for regular range use.
