Want more rounds on your shotgun without reloading? This Carlson's magazine tube extension adds a whopping 10-shot capacity to your Benelli Nova, Benelli Super Nova, or Beretta 1301 shotgun. It's for 12 gauge models, made by the reputable Carlson's brand (part number 04510). The extension tube is black and screws right onto the end of your existing magazine, giving you way more firepower for competition, hunting, or home defense. It's brand new in its packaging. Installation is usually straightforward, but always check your local laws about magazine capacity – some areas have restrictions. Carlson's is known for quality, so you know it's built tough. Whether you're a 3-gun competitor, a waterfowl hunter who wants extra shells, or just a shotgun enthusiast, this extension is a popular and reliable upgrade. It just makes your scattergun that much more capable and fun to shoot. (Comes with a Prop 65 warning for California customers.)
