My 3 year old Super Nova has developed a problem - the fore arm remains locked after firing so the spent shell can't be ejected and the second shell loaded. If I press the breech bolt latch, the fore end will slide back and allow the spent shell to be ejected and the second shell to be loaded. Obviously, this is a problem since the second and third shots are important when duck hunting. Has anyone else run into this problem? Any idea what the problem might be and how to fix it?
