A little longer than i thought - FCW Tristar Viper G2 Magazine Extention

Installed on a TriStar viper G2. I would have given it five stars, but it did not come with the tube barrel clamp. It installed easy, I cut the spring at the recommended length about 12 inches past the end of the barrel, and it cycled perfectly. The tube extends about 2 inches past the end of the barrel, which I was not expecting but functions fine. The extended tube holds 10 3 inch shells and one of the chamber for a total of 11 shots. It is lightweight and one of the better extended tubes I’ve used thus far.
