Hey I got some questions for you guys? I just picked up a 870 express mag 4 +1 with a 18 1/2 inch barrel my first tactual type shotgun, so I would like to upgrade it with some parts and I need some of your guys opinions on quality parts. I would like to put on an extended magazine tube, side saddle and new forend grip. Whats a better mag extensions? -Willson combat -choate extinction -remington -TacStar Side Saddles? -TacStar -Mesa Tac Any advice you guys have is appreciated thanks. Wanna kill these ads?
