The AKS-74 is an AKMS, and the shotgun appears to be a Mossberg 500 with a home-made stock. --Funkychinaman (talk) 15:31, 15 January 2015 (EST)
Its not a Mossberg, most obvious differences are the shape of the bracket that attaches the barrel and mag tube together, and the trigger guard that is more like an 870 shape. I do not think the stock is actually home made either (despite the rather crude appearance), but rather the gun is a Baikal IL-81 "Fox Terrier":Error creating thumbnail: File missingBaikal IL-81 "Fox Terrier" - 12 gauge--commando552 (talk) 17:13, 15 January 2015 (EST)
Also, I think that Lewis Gun is just a dressed up version of a DP28 seen in a lot of Soviet and Russian movies, like The State Border series.
