Correct, the stock and receiver are one piece on a Nova. The SuperNova has a more traditional stock. It comes with a comfortech stock like the SBE. Add me to the list of people who love their Nova. I've hunted with mine for almost 20 years. I've also won my class in the pump gun event at Colorado State Sporting Clays state championship many times. Which in my opinion, is a testament to their build quality and how well they shoot. I've even used mine in manual division 3 gun matches (when a division like that exists). The guns flat out run! The only parts I've replaced are the right and left shell latches. Both 10 dollar parts. Both the Nova and Supernova are also 3.5 chambers if that matters.
