http://www.gunsnet.net/Linx310/index.shtml is an excellent source of information for those who are interested in Romanian AK rifles. There is a very good tutorial (with pictures) section that that thoroughly describes how to correct most of the faults common to the rifle such as canted front sights and canted gas blocks.
There is also a section that gives a brief thumbnail description of the various Romanian AK models. The strengths and shortcomings of each are presented.
