Tacstar® continues its position as a leader in top quality, high-tech shotgun accessories with the introduction of carbon fiber magazine extensions tubes. The new carbon fiber magazine extensions are much lighter than traditional steel tubes and are even more durable. The weight savings maintain the shotgun’s fast-handling nature making it the perfect upgrade for competition, bird and waterfowl, and personal defense shotguns. Each magazine extension comes with a machined aluminum high-visibility follower, magazine spring, and barrel magazine clamp for rock solid stability. Tacstar carbon fiber magazine extensions are available in 7-shot, 8-shot, and 10-shot capacities. The 7-shot adds 2 rounds, the 8-shot adds 3 rounds and the 10-shot adds 5 rounds to your shotgun's capacity.
