My bet is the “weapons”may be of the airsoft variety.
As a self declared expert in airsoft weaponry, I can definitively say, it’s nearly impossible to tell from a photo. The bottom of the mag is one way to tell, but can’t see any in that pic.
The shotgun is “real steal” (an airsoft community term for real guns, and components for real guns), but the AK and the FN, I’m betting are airsoft.
The grenade launcher is the give away. Not likely he obtained a real one, but airsoft ones are common as dirt.
The scope on the FN is a Aim Sports 1.5-4x30 CQB “Recon Series”. They are very commonly used on airsoft guns. They are actually “real steal” capable, but are of reasonable price, about $120, so that makes them popular.
I that exact one mounted on one of my airsoft ARs.
I’m going out on a limb and declaring the FN to be airsoft.
Whos going spend $3,500 on a gun, $10,000 on a grenade launcher...and mount a $120 airsoft scope.
I don’t think so.
