EDIT: The N7 decal was too obviously a square sticker so I cut parts away and painted a black stripe to continue the black of the decal background along the gun.
This is an Airsoft Rifle I got because the shape reminded me of my favorite games ever created by mankind, Mass Effect.
It was surprisingly powerful and accurate, firing through cardboard boxes and messing up a Sunny D jug nicely.
I repainted it and added the N7 decal.
Its on Ebay now. [link]
