DIFFERENCE BETWEEN NIGHT QUEST AND NIGHT ENFORCER:

What is the difference between a Night Quest PVS-14 and a Night Enforcer PVS-14 manufactured by ITT?

There is no difference. They are exactly the same product. The names used only define the market for which they are intended for by the manufacturer.

In other words, if you buy a Night Enforcer, you are getting a Night Quest. If you buy a Night Quest, you are getting Night Enforcer.

It's all good.
