"Say hello to my little friend" I just picked this Model #50420 up Fri at Big 5 and payed way too much for it but I wanted it because unlike the one pictured up at Mossberg.com it did not have the cheese grater tri rail on the foregrip, apparently that is a different model. I have a small Tri Rail setup coming that is small enough to fit on whats left of the magazine tube, other than that what is your favorite place to get goodies for a Mossberg 500 online?
