Way better then Norks, but look at the models more closely.... Some have standard ports/arched msh as well. Basically there should be a SAM to meet your needs. They have old school GI, mid-school enhanced GI, and full modern with most of the bells/rails you could ask for. I have 2 so far and have been very impressed with both.
Quality of the steel/parts/fitting would be pretty much the same with IJ/SAM
