The verifiers net still exists, but it is not going to be maintained or built up on. While the businesses can verify, many will not do guns that are not part of their inventory. Like the guy at my local gunstore said...there are likely 20, 000 guns in the area and he's not going to verify them all.
The guys who presently are qualified verifiers can continue to do so, alhtough by what I hear, they cannot verify restricted guns that aren't registered.
I just had a bunch of guns verified (so they could be registered) this morning by my local firearms officer. He has always been happy to do so, and is paid for his troubles at that.
