What Is the Recommended Break-in Period for the Century Arms AP5?

The AP5 utilizes a roller-delayed blowback locking design. Firearms operating on this principle may require discharge of approximately 500 rounds to break-in. During the 500 round break-in period, it is recommended to use Factory New 124 grain NATO or +P 9mm ammunition.

Please be sure to properly lubricate and clean the firearm throughout the break-in period in accordance with instructions in the firearm manual.

Can I Use +P Ammunition in my Century Arms AP5?

Yes, the AP5 can be used with +P ammunition. However, the AP5 is not rated for +P+ ammunition.

What Ammunition Will Perform Better in my Century Arms AP5?

Firearm loading and feeding will be best with full metal jacketed round nose ammunition. Most commonly available 9mm (also referred to as 9×19mm or 9mm Luger) ammunition should function in the Century Arms AP5.

Can I Use A Suppressor with My Century Arms AP5?

Suppressor ownership is subject to National Firearms Act licensing and Tax Stamp requirements. Please contact your local BATFE office for proper application and approval information to acquire a suppressor. If your Century Arms AP5 variant utilizes the 3-lug adapter, a suppressor can be used with your firearm once legally obtained.

Can I add a stock to my Century Arms AP5?

The Century Arms AP5 is a pistol as determined by the BATFE, and adding a stock would convert the firearm to a Short Barrel Rifle (SBR). Therefore, adding a stock to your Century Arms AP5 can only be done after obtaining proper approval from the ATF, as well as any applicable State or Federal Entity.

Adding a stock to your Century Arms AP5 without proper approval would violate the National Firearms Act, and would result in Federal or State criminal prosecution. Consult any applicable Local, State, and Federal Law Enforcement agencies prior to making any function or operation changes to your firearm.
