They are made for export to the US. Usually they are not made from demilled military weapons as are many AK-clones but from parts made in the same factory, Cugir in Romania, that builds Romanian military rifles. Therefore, the parts might or might not be Milspec.
The receivers do not have dimples - since they are/were intended as lo-cap weapons using single-stack mags, the magwells have been ground out to accept standard hi-cap AK mags. Since these rifles do not have dimples (Intended to lock the mag in place and eliminate side to side wobble) the receivers have rails tacked on the inside to serve the same purpose.
The wood stocks are pretty rough and unfinished.
The Romanian FCG's were made, IIRC, from select fire FCG's and the machine work is not well done. They are prone to trigger slap and have a lot of creep. Most these days use the Tapco G2 trigger, a great improvement.
Some had bayonet lugs and muzzle attachments, some did not. Some were imported with thumbhole stocks but most with pistol grips.
Front sight posts are sometimes canted, a few have canted gas blocks. Usually the canted sight is an easy fix.
They are rougher overall than the majority of AK clones, but they shoot when you pull the trigger.
Get a good one and it will perform as well as an Arsenal build that costs 2-3 times as much as the WASR.
