Does not work well with magpul forend - GG&G Mossberg 590 Sling & Flashlight Mount Combo

I wanted this mount to avoid having a light mounted of the forend of my 590. From the picture of the product on website it appeared just like how I wanted it. However, with the Magpul forend, it interferes with the action when the product is mounted with the rail facing towards the stock. It can be mounted towards the front but it feels less secure due to the indent pins not lining up. I would recommend this product for someone not using a magpul forend, or for someone who wouldn't mind making modifications to their magpul forend.
