After loading your SuperNova, does the carrier stay depressed or spring back out? Mine stays depressed which causes the next racked load to be shucked out the bottom of the gun instead of riding on the carrier up to the chamber. It's like the carrier does not fall down quick enough to catch the next shell out of the magazine. When depressing the carrier it will "click" at a certain point after which the carrier stays depressed and you have to manually pull it out to get it to feed properly. If everybody elses springs back out after loading I'm sending mine in to get fixed.
