I just joined the site and haven't looked around too much, but this is a topic I needed to get in on. I have a 2015 Mossberg Patriot in .308. My original magazine hold 5 with no problem. I was told by Mossberg last year that since the Patriot was a new version additional magazines would not be available till 2016. So I call them and now they say they only make the 4x4 magazine for the Patriot and have no plans to make a 5 round magazine. The customer service person "said" she talked to a tech who "said" the magazine on a Patriot is only a 4 round magazine. The owner's manual even says the non-magnum or standard caliber magazine holds 5. So I have sent a copy of that part of the manual to Mossberg and am asking does the 4x4 magazine actually hold 5 or not? I am not going to buy something and have to turn around & return it. Anybody here bought any of the 4x4 mags? Does it hold 5 rounds of .308? Thanks for any help.
