I am wanting to purchase this for my Mossberg 500 Persuader: http://www.midwayusa.com/product/734544/mako-3-rail-forend-mossberg-500-590-polymer-black?cm_vc=S014 and was wondering if any one here has installed one on there Persuader? I got mine this year (2012) it has a 20'' barrel w/ pistol grip, heat shield and holds 8 rounds, so I was wondering if I would need to buy any addition parts to make this fit properly? Or special tools to take the old hand guard off. I never worked on a shot gun before. All I know is if I unscrew the magazine tube cap I can change the barrel out but never went further then that. All so looking at may be getting this one if my first option fails: http://www.midwayusa.com/product/33...p-mossberg-500-600-synthetic-black?cm_vc=S014 Thanks for your time!
