Strike industries voa handguard didnt dit my mossberg 500 bantam - Strike Industries Valor of Action 10 M-Lok Handguard for Mossberg 500

The handguard itself felt solid and I loved the location and options of all the MLOK mounts, however when I went to install it in my Mossberg 500 I was not able to get the captive nut to screw on and attach. I messaged strike industries for an answer and they responded in a timely manner but it took me a little bit to figure out what model I had as they kept asking for the specific model besides just 500. Based off what I saw Walmart sells I told them the Bantam but have not received another message from them in a few weeks now. I was a bit disappointed as it said it fits the 500 series so did not expect an issue and now am getting no communication back from the company. Handguard looks and feels great but since I can’t actually attach it to my shotgun I can’t fully function check it and that’s why I have it a 3, almost a 2 because I have another a hundred part that I can’t use and getting no information on.
