As far as I can tell from that webpage, it looks like an EOtech with a 3x magnifier built into a single mount. From their webpage "http://www.eotechinc.com/holographic-weapons-technology/ballistic-reticle-information" the "-4" at the end of the model number means the reticle comes with four dots calibrated for 5.56/.223 bullet drop at various ranges. For an AK, you could simply get the regular EOtech reticle( the "-0", no BDC), or maybe try the .300 BLK one since it would have similar ballistics to 7.62x39. A disadvantage to using EOtechs in general in AKs is that they're designed with the AR in mind with respect to the optics height over bore(You will need a cheekrest to avoid a chinweld on the stock). Another option to consider besides the EOtech with a magnifier, is a 1-4x scope with an illuminated reticle and a true 1x setting so it can be used like a red dot. There are several good options for that kind of optic at your 1K price point, but I'm not sure what the options are for a 7.62x39 BDC on those scopes. Not sure any of this is worth the money, depends what you're trying to do exactly. If you just want a red dot, I'd recommend an aimpoint.
