The Beretta pistol appears to be a 92FS, the penultimate gun is a MAC 10, and the last gun is an HK416. --commando552 (talk) 20:19, 26 July 2016 (EDT)
Thanks! I've just stumbled upon HK416 elsewhere and thought that it is indeed, it. As for MAC 10 I'm not so sure though - with this being the clearest image it's somewhat hard to tell. --Kloga (talk) 20:23, 26 July 2016 (EDT)
The PDWs are mockups - note the SEF lowers. StanTheMan (talk) 01:50, 4 October 2016 (EDT)

The shotgun seen in the background of images #4/5/6 looks very much like a Winchester Model 1300 with extended magazine tube, PeeWee055 (talk) 09:07, 31 July 2016 (EDT)
I took the liberty to add the Winchester Model 1300 on the page, seems like a reasonable guestimate, PeeWee055 (talk) 07:41, 6 August 2016 (EDT)
The first cap in the section on the page shows what looks to be a longer pump grip with finer ribbing centered up - I think it's actually a Mossberg 590 without bayonet lug. StanTheMan (talk) 01:50, 4 October 2016 (EDT)
