I have a Century AR-15 that is a tack driver. Never jams no matter how many times I shoot and don't clean it. I reckon even a blind squirrel sometimes finds a nut.
You may have one of the few good ones they ever made. Other people have had such poorly assembled AR’s from Century that they had kabooms on the first pull of the trigger.
They even manage to screw up what was previously thought to be impossible to screw up - Century has made unusable and non-working AKs!
