Basically, I prefer bead sights to ghost ring sights and want a traditional stock, but want to keep a Supernova because they're such badass shotguns. So that leaves me with just doing a straight trade for the model with the vent rib. My shotgun is in great condition, with only a little rub in the finish on the barrel that's about an inch long. Hardly noticeable. I've put a picture of it below:
I'll keep the extended magazine tube on mine unless you've already got one on yours, but otherwise what you see is what you get.
I'm currently located in Kerrville, but over the next few weeks I'll be driving back and forth from here to Waco, Richardson, and Temple. So if you're between here and there, we can meet up.
Please PM me for the fastest response. I will only check this thread once a day, so you might be waiting a while for a response.
