Any opinions on Promag M4 stock for 870?

[buddah]

Has anyone ever used the promag AR-15 style collapsible stock on a Remmy 870 or Mossy 590?? I saw the item on www.midwayusa.com. The item # is 293926. It has 3 shell holders built above the pistol grip. I currently have a fixed speedfeed stock on my shotty and I am not fond of the sidesaddle. Thanks in advance for your advice.

I don't have one, but it looks cheap to me. I don't have one, but maybe this will work for you. http://www.knoxx.com/products/PowerPak.php
