There has been a great deal of discussion on "sight improvements" for the AK. Those who don't understand the rifles and compare them (intentionally or not) to the AR system think the sights are a weakness of the AK system. I disagree.
Research and corroboration by others has shown that the majority of today's rifle encounters in all three worlds of police, military and private citizen tend to be inside 100 yards. Many actually inside of 25 yards.
We also know from experience as well as FOF training that the shooting range is not reality, but rather an artificial environment intended to prepare you for the fight. Sights that are intended to give you an edge on the range for qualifications, may not be the best choice for use in a fight.
The traditional "peep" type sights found on US Rifles beginning (I believe) with the 1903-A3 are fine for gravel belly long range shooting. However, I have found, and it is my opinion, that they are slower in the CQB environment than the open "tangent" sights found on the stock AK.
With the standard AK sights (or improved versions as sold on OST), you get the same sight picture as you do with a pistol. If you also have a shotgun in the battery, the standard rifle sights sold by most shotgun companies (NOT the ghost ring) can be looked at the same way.
Having the same sight picture for all of your shooting cannot be ignored as an advantage. Given that we anticipate our contacts to be within 100 yards, this is a great advantage.
The standard AK sights allow you to use the Front Sight Assembly "ONLY" for sight verification inside 15 yards. This was first written about by Suarez International Staff Instructor Randy Harris (Cruel Hand Luke). As the rifle is shouldered, you are looking at the adversary/target. The rifle will appear in the peripheral visual field.
Traditional shooting methods have you look throught he rear notch at the front post and refine the sight picture as you press the trigger. With the FSA shooting (Front Sight Assembly) method, you ignore the rear sight and still visually focus on the target. When the FSA appears surrounded by the target, you go. If it is a little farther, you can "notice the FSA a little more as you press.
The results are faster hits on the bad guy in a fraction of the time it would take for the use of traditiona methods. The accuracy is not shirt button groups, but rather MOH (Minute of Hadji). That is just fine in my perspective.
I have tried to replicate this with apperture sighted rifles and it is much harder to accomplish. Knowing how to use the AK sight system this way in CQB is as fast as using a red dot sight.
For longer shooting problems, you use the sights as traditionally indicated. The front post is level with the top edge of the rear notch. You set it up so you can see equal amounts of light on either side of the front sight post. Hold that steady while you p-r-e-s-s.
At out current range in Northern AZ there is a man sized steel gong at 180 yards. At the AK classes this year, just for fun, we hit the thing repeatedly with our AKs. We did it with high dollar Krebs Customs, and with WASR10s, and with shorty Suchka rifles. All of them with stock AK sights.
Now if we were on our bellies at Camp Perry shooting at 1000 yards, the apperture sighted rifles would have an edge. But rather than try to conform your rifle to their standards ask yourself this - what type of fight is more likely for you, a shot across a canyon, or a shot across the parking lot.
Learn to use the AK sight platform as it is. I think you will learn to like it as it came.
