I am a civilian.

He is a LEO.

Can I sell a long gun to him without needing to use a FFL?

I think this bill became law in its form.

I don't seen an exemption between a civilian and a LEO. So, IMO, no. You need to go tru an FFL

F2F transfers for long guns from LEO to LEO only do not require an FFL.

Short answer to your question:

NO, unless he is immediate family

Thanks all. That is what I thought, but I wanted to hear voices smarter than I. FFL it is.....
