TacStar continues their position as a leader in top quality, high tech shotgun accessories with the introduction of Carbon Fiber magazine extensions. Carbon fiber offers an unbeatable strength to weight ratio. These extensions are about 4 times lighter than traditional steel tubes, however they are much stronger. The carbon fiber offers durability and toughness to go along with light weight, making it the perfect material for extension tubes. As an example, with the 10 shot extension, you save nearly a half a pound using the carbon fiber tube compared to a steel tube. In addition, we also include a high visibility follower which is machined out of solid aluminum and is designed to improve feeding as well as a barrel magazine clamp. The extensions are available in 7 shot, 8 shot and 10 shot capacities. The 7 shot extension adds 2 rounds, the 8 shot adds 3 rounds and the 10 shot adds 5 rounds to your shotguns total capacity.
