I don't recall posting about this one, but found it late summer/early fall in an out of the way funshop. It's a Century-marked Imbel Gear Logo receiver upon which someone (maybe CAI) built up an Izzy parts kit with a 16.5" barrel. It's got the requisite US parts to be 922r compliant. It was filthy inside and I spent about four hours cleaning it and correctly installing the gas tube. I suspect the former owner had problems with it not cycling, but I didn't fire it before effecting repairs.
When I did get to the range, it was spot-on with SA surplus and Port at 100 to 200 yds. By that, I mean I hit everything I shot at. Took a few hots at the 440 yd gong and hit it 3/5 offhand. Functionality with three mags was 100%. Muzzle blast was not that bad, even under a the shed roof overhead of the range benches.
Oh, did I mention I got it for $400 OTD?
I figured if it was a POS I'd part it out and still be ahead, but it's a keeper.
