The Maadis imported by Steyr were very high quality guns.
The later CAI Maadis apparently varied from OK to POS. The example I owned was from the extreme lower end of that scale. Literally, the only good thing about that rifle was that it would cycle reliably. The wood was horrible and slathered with stnky varnish. The metal was finished with paint that was flaking as the gun came from the box. AK's have only a couple screws, but they buggered the heads on them at the factory. The front sight was so badly canted that the gun could not be zeroed even at 25 yards. Mechanical accuracy was very poor; fist-sized groups at 25 yards that opened up from there. The trigger slap with each shot did not make the gun any more enjoyable.
So, I stripped and refinished the whole thing. Replaced the rear sight with an RPK sight, then the front sight with an ACE gas block sight.
With the new sights, it became possible to center the gigantic groups on paper, but they were still gigantic. I gave up on it. A friend bought it from me because he liked the way it looked after my mods.
Before you buy a Maadi, shoot it if possible or see it shot. As for me, I've bought a couple more AK's since then, but I've no desire for another Maadi.
