John walked quietly with his gun out and ready, when he stumbled upon an area with burnt rug, ruined walls, a shattered windows a blood splattered all over the place. This must be the place he heard the explosion just a bit earlier.

He looked down, and noticed, right by the wall, an assault rifle. Aside from some blood, it seemed to be in perfect condition. 

John reached down and picked it up. As he moved it, a red laser moved across the wall. A laser sight, it was coming from the scope, which appeared digital. John messed with it a bit. You could look up to a mile away with it.

He dropped the clip into his hands and checked the rounds. 50. rounds. Made for taking down big, tough opponents no doubt. You could switch between single fire and full auto too. The best part was...another clip lay on the ground by a fee drops of blood. Excellent.

John put his glock in his holster, and walked with the assault rifle ready instead.
