No, barrels could be several months out of receiver (3 or so depending on mfg) if its more than that its getting more like a replacement.

Your SN should be more in the 9 to 11/18 range.

Or to shift it around, the barrel would match up with a 220xxx date receiver.

always possible a misplaced receiver got fed in, other may have better info but straight up it looks like a replacement.
