  • Just what I was looking for.
    Verified Purchase

    This item was just as described and was delivered in a very timely manor.The for grip had to be fitted as it was binding against my Mossberg 590's heavy walled barrel.Ihad to file the top of the grip for clearence when pulled back to pump the action.It works well now.

  • Doesn't really fit.
    Verified Purchase

    Forewarned! According to ProMag, Mossberg made pre-2008 500 series shotguns with various slide lengths. Their product only fits 2 of the slide lengths without any modification. When the slide did not fit my gun with (too long) or with out (too short) the extender I called Pro-Mag. Their representative told me to cut the extender down to length and I would have no problem. Wrong. Once I cut the part, the nut from the slide will not fit into the extender to reach the threads. The extender is now cut and worthless. The new forearm piece moves front to back about 1/2 inch before engaging the slide. Unacceptable. The buttstock seems to fit an work fine.

    Easily installed and fits perfectly. My only complaint would be the strong "rubber smell" of the buttplate pad. I'm leaving it out in the open air for a while to breath.

    Verified Purchase

    Had no problems with assembly once I figured out how to asemble product. Fit great and looks awesome. Just a little worried about the forgrip but it performed fine when fired in rapid succession.

  • Great bargain for this item!
    Verified Purchase

    This was my first time doing any gun modifications like this. The directions were easy enough to use out of the box (but youtube videos made it even easier). The promag stock and pistol grip set was absolutely awesome. It changed the entire look and functionality of my 40 year old mossberg 500. It now looks almost as good as anything purchased for 400 or more off the gun rack. Stock is sturdy and fit well. The forearm was easy to replace and has a nice feel. I am very pleased with this product.

  • Fits like a glove.
    Verified Purchase

    Great price, I've seen just the fore-arm section made by other manufacturers priced at fifty bucks, and here you get the whole kit & kaboodle for about $73.00. All the parts fit my Mossberg perfectly, they even warn you it will only fit the older models. It even came with the tools needed to dis-assemble and assemble the components.
