1984 Gun Megatron had the ability to convert his entire body into a power riffle gun. every ounce of his body could emit a strong fire power in gun mode to hit/destroy his enemies. Megatron was the very first targetmaster. as he could transform his body into a gun & other transformers could fire the gun/riffle alt mode. I really loved 1984 Gun/Riffle megatron's alt mode because it was unique & no other transformers at that time had such a different special alt mode. often times when their were various transformers with similar or exact alt modes. those transformers just didn't seem that special nor unique.
