Im a little skeptical of these.. The Black Aces never really took off, the custom aftermarket kits never really took off. Everything is so friggin expensive for them, it defeats the purpose of a shot gun being a true utility firearm. It's recreating the wheel in my eyes and have no want for one lol. Not to mention, those mags are going to be a real PITA to haul around for any "tacticool" application.
