His t-shirt should read “I made the world’s most prolific rifle and I’ll got was this lousy t-shirt!!!”

Nossir. To see how the grammar is actually impeccable, do the following:

An aide to the 93-year-old father of the AK-47 said Kalashnikov had been (having heart problems) and (feeling poorly) since March.

Deconstruct the sentence to use each clause one at a time.

An aide to the 93-year-old father of the AK-47 said Kalashnikov had been having heart problems since March. *PERMISSIBLE*

An aide to the 93-year-old father of the AK-47 said Kalashnikov had been feeling poorly since March. *PERMISSIBLE*

The sentence gots good grammerz.
