Gun Identification

[Gunner313]

I have never been able to identify the weapon under the M4 in this picture. It is from Babylon AD. When I first did the page I labled it unknown, which someone then claimed it was a Spas 15 which it clearly is not.

I would really like to lable this weapon correctly.

It looks kind of like a semi auto shotgun. Looks very similar to the Spas 12 with a fixed pistol grip stock, except the forend starts at the reciver.

I find it odd they would use a weapon that is so unknown and then just throw it in the trunk.

One last thought maybe it is a toy or a modified airsoft gun.
