Gun came with a zendl brake too. Note that's the right hand version, so if you're a lefty you'll want to get rid of it (more ports to outside edge to push weapon into your body's center mass and minimizing twisting as recoil shoves to just one side). But they're great brakes.
For the fixed stock and that optic height, a padded cheek rest/riser is a good idea. For stock pad/extension, the UTG soft rubber AK stock pads fit pretty well. If you're running body armor or winter clothing, you won't need but in the summer most folks will find any OE VZ58 stocks too short.
Other thoughts -- OE pistol grips are pretty short for most folks. Ronin grips make OE profile ones in various colors, though obviously won't look as nice as the OE wood. Also w/ the OE wood furniture. If you run your weapon really hot, you should expect the upper hg to crack. Not a matter of if, but when. Wouldn't hurt to get a beaver barf top cover to run at the range and keep the wood for display/safe. Lower doesn't matter so much, but also wouldn't hurt to get one of the heat shields for the lower. One of the members here can probably point you to the fellow who makes them. Used to list on ebay, but haven't seen recently.
Congrats on your purchase. And welcome.
