What's the name of this old Sci Fi movie?

I watched it a couple times but can't remember the name or actors..It's from the 70s or early 80s. The story line is about a guy that gets infected by a alien force visiting Earth. I remember He has this stone like thing embeded in his chest that is making him sick and turn evil. He also finds a Cannon like lazer gun that his entire arm fits into up to his elbow that he uses to blow up things. I also remember the aliens coming down in a spaceship and they both looked like dinosaurs...Please help..

    Alien creatures kill a mutated alien creature in the California desert. Its remains, and the high-tech laser gun and power source accidentally left behind, are found by a teenager. However, the power source causes the teenager to mutate too, and he goes on a murderous rampage.
