An ATN 5X33L is mounted on my Bushy Shorty AK. Put there cause it was in the parts bin when we finished-out the rifle. THERE ARE BETTER SCOPES OUT THERE but this particular ATN works fine for me. The factory mount is a POS but it WILL tighten down and stay in place. The optics are mediocre but not bad. It holds zero and the bullet drop compensator is fun to use if not particularly accurate. The illuminated reticle is DAMN SURE RED, must have something to do with it coming from a ex-COMBLOC country. One reason I like the scope is it sits as low as possible on the rifle with M4 handguards in place, and I mean ONE YOUNG RCH over the plastic. The ATN has about a MILE of adjustment in it as Lordtrader will testify. YOU DO NOT NEED A FLIP-DOWN FRONT SIGHT. The focal length of the 5X33L won't begin to resolve the front sight on my M4. You look right through the front sight like it isn't there. It ain't pretty, it is heavy, everybody badmouths them but the 5X33L works for me.
