Problems I see with this model are:
1) the Fastfire itself. I don't care for open-type dot sights in general, having owned a couple, seen a couple more, and being unimpressed with all of them
2) of the open-type dot sights, the Burris is on the lower end of the quality/price spectrum; a Docter or Pride-Fowler might be a better option
3) the integrated rear sight does not appear to have any provision for elevation adjustment, and it precludes the use of RPK sights, peep sights, night sights, express sights, etc.
The advantages are that it's lightweight, low-profile, and will work with any AK out there (except the AKS-74U), regardless of receiver type, stock type or siderail configuration (or lack thereof).
And it's relatively affordable, at under $300 for the optic *and* mount. Future versions incorporating different optics will of course be more expensive.
I applaud Mr. LaRue for breaking into the AK market. Although this product wasn't what I was anticipating and doesn't make my "gotta have" list, I'm sure it will be an excellent solution for a lot of folks. I hope he brings out a similar mount for the Aimpoint Micro in the near future, and makes the mount itself available separately for those who already have an Aimpoint to use.
