Enjoy. They are a blast to shoot and the Chicoms make a good AK. It is a little tough to soup it up in that they have a few differences with the Euro's. Most spareparts out there are to Euro specs but it sounds as if you have that little problem solved for you. If you need a new trigger for some reason I rec the Redstar trigger. In the MAK, however, you'll need to grind(dremel) some material off the selector lever yolk. Once again, it also, is made to Euro specs.
The MAK can be pretty accurate. With a little practice I can get mine close to what I get with my AR's.
Make sure it has the requisite number of american parts. BATF won't care what someone else told you. You need to change out 5 parts on the stamped AK's like the MAK, 6 parts if you put a muzzle break or comp on it. It is easy enough to do.
