Frequently Asked Questions

What is the operating system of the Century Dynamics BF12 shotgun?

The Century Dynamics BF12 shotgun features a semi-automatic, short-stroke piston operated system. This means a piston uses gas pressure to cycle operating rods, which in turn work the bolt for reliable cycling of rounds.

What are the key construction materials for the Century Dynamics BF12?

The barrel is made of 4140 chrome moly steel, while the upper receiver and handguard are constructed from 7075 T6 aluminum. The lower receiver is primarily polymer (around 90%), contributing to its overall weight and cost-effectiveness.

How reliable are the magazines for the Century Dynamics BF12?

The 5 and 10-round Mark 1919 style magazines are reported to be extremely reliable. The 20-round ProMag drums are noted as being more finicky but still performed acceptably during testing.

What are the main drawbacks of the Century Dynamics BF12's trigger?

The trigger in the BF12 is a significant drawback due to its bullpup design. It features a long steel rod connection, resulting in a heavy, gritty, and stagey feel, estimated between 10-12 pounds, which limits rapid firing capability.

Is the Century Dynamics BF12 recommended for home defense?

The reviewer does not personally recommend the BF12 for serious home defense due to concerns about plastic shotgun shells deforming over time. They prefer AR-style platforms for home defense due to lower recoil and higher round capacity.
