Back in the 1970s, I bought a SAC grade a 20 gauge with 28 Krupp Steel barrels. I had the automatic ejectors with a switch in the forend so you could cut them on or off at will. It weighed a full 7 lbs was full choked in both barrels but I could shoot it reasonably well on some clay birds thrown with a "Trius" portable trap.
THEN I ad occasion to look inside the action. I have never seen such a rough finished gun before or since. Parts looked as if they had been hewed out with a foot Adz. The insides of a Birmingham proofed W Richards (Low-grade J P Clabrough) looked like a Purdey in comparison.
I fixed whatever it was I had to take it apart for, Buttoned it back up & traded it off at first opportunity & never looked back. I still have no desire to ever own another SAC shotgun.
I understand quality fell off near the end of production, mine must have been the last. I sincerely hope yours is an earlier one & much better finished internally. Mine looked decent on the outside, but a view of the inner works just made you sick at your stomach for what was supposedly a ""Quality" double.
