Did the Dickye Amendment Actually Ban Federal Funding of Gun Research?

Dicky's amendment led to congress basically defunding gun research. The irony is, towards the end of dicky's life, he actually said that was a mistake. I've gone back through it in my mind to say, what could we have done? And i know what we could have done. We could have kept the fund alive and just restricted the expenditure of dollars. It took a couple of more years to get those appropriations back.
