When evaluating a claim such as the OP described, you need to take into account many component errors to arrive with the system error or what is observed on the target. The aiming error is but one component. We know that there are folk that can hold hard at mid and long range with iron sights even with a shorter sight radius than what Mr Matthews used. But what it also takes are the other components to have minimal error as well. The main question I have is whether the rifle and ammo were consistently capable of such a feat. Like I mentioned earlier, the FAL is no M16 nor an M14. Environmental conditions would be another component error contributor. Measurement criteria (how many shots in the group?, how many groups? etc) is another significant unknown factor. Almost anyone can put two shots close together at distance once in their life.
