Hi there Doug, and welcome here!
A quick guide for you:
"Tilbehør og Utstyr
" is the forum for kit and accessories. There is also a post about norwegian(norsk) equipment.
" is weaponsrelated stuff, and for those realsim kits you should check out the Impression
forum. There is a couple of very good Norwegian Army impressions in there - FSK and TMBN.
For sales of equipment it is Utstyr - Salg og auksjon
that is your place to be. Weapons are being sold in the Våpen - Salg og auksjon
