I am a long time user of these 760 / 7600 series. They have a free float barrel - the pump mechanism rides on an action tube parallel to and under the barrel, and they have a reasonably tight lockup. The more you use them, the smoother they get. I’ve had one factory defect that was buggered from new with a badly machined bolt face that wouldn’t hold the extractor clip in place, (rifle was replaced under warranty) but one could argue that QC issues for ANY Remington product is unsuprising these days.

I currently have an old 760 in .30-06 that dates back to the 1960s and it is VERY well used and is liquid smooth and accurate.

They can be accurized very nicely......

The weak point of these rifles is the stamped steel detachable magazine box but that can be remedied by getting a couple of spares and weeding out the ones that cause issues.
