Yeah, my criticism was directed at the sight radius. I already don't like how short the standard AK sight radius is, and this makes it even shorter! Shorter is definitely less precise. Moving the front sight rearward also makes the post appear fatter in your sight picture. A standard AK front post is already on the fat side. Also, if the rear sight is marked the same as a regular AK, making the sight radius shorter will make the elevation settings no longer accurate for the ranges they are marked for.
Yeah, an aperture rear sight would help, but it's even better with an aperture rear and the front sight in the original place, out on the end of the barrel. That gives them the same sight radius as a 20" barreled AR.
The weight savings from a gas block front sight would be minuscule. And it's not as if the standard 6.5 lb. AK is slow to point or anything, with the original front sight. I just think any possible benefits of that setup would be outweighed by the downsides of having such short sight radius.
But I'm in total agreeance that a nice co-witnessed red dot is the way to go. The iron sights become less of an issue then, though I do like to have them for backup.
Kudos for using chrome-lined barrels on these, too. Most American-made barrels skip that feature, which I think is very important on this kind of rifle, especially considering the kind of ammo that is usually run through them.
