This Navy variant ships with a RAL8000 FDE finish and is based on the roller-delayed blowback AP5 platform. The threaded 8.9-inch barrel is paired with the Navy configuration designation.

Owners of the Century Arms AP5 in the Navy configuration consistently mention the RAL8000 FDE finish as one of the better-looking treatments on a 9mm pistol-format carbine at this price point. The 8.9-inch barrel length and 30-round magazine capacity are the core appeal for range use.

The AP5 platform's roller-delayed action draws most of the praise; owners report smooth cycling and reliable feeding across a wide range of 9mm ammunition. The Navy designation and threaded barrel make it popular for suppressor-ready builds, though owners note the 8.9-inch barrel puts it in a niche between a compact pistol and a full-length carbine.

Century Arms quality control is a recurring discussion point. Most buyers report good out-of-the-box function, but the occasional fit-and-finish complaint surfaces. Aftermarket support for the AP5 platform has grown, and holster and accessory options are more available than they were at the platform's US introduction.
