The Century Arms Centurion A4 (Century Arms part no. SG8871-N) is a 12 gauge semi-automatic shotgun built for shooters who want dependable follow-up shots without a premium price tag. A black synthetic stock and forend give it a durable, low-maintenance profile suited to the field, the range, or home-defense duty. The semi-automatic action cycles each shell automatically, so you can stay on target for faster, more efficient strings of fire than a pump gun allows. It’s a straightforward, no-frills shotgun built to run.
