I have a 14" 590A1, and put a Boyd's laminate stock and forend set on it. I didn't realize the forends were different lengths for the standard barrel lengths and the 14" barrel, so when it arrived I had to do some cutting and sanding to make the forend fit. Now it actually slides over front barrel lug thing that goes over the magazine, just behind the magazine cap. Since the forend was for a standard length Mossberg, I imagine you'll have to do some modification to make a Hogue fit (if modifications are even possible).
