There are very, very few semi-automatic mass produced rifles that regularly can get 1 1/2 MOA groups at 100 yards. Add a free float rail, SS barrel and a good optic and most AR15s can put bullets through the same hole all day long at 100, and keep it under 2 MOA out to 300, even 500 yards.

Is it the design? Ballistics? I'm not a believer in "xxx caliber is more accurate than xxx", but it makes sense that a flat trajectory 3000 fps 5.56 would be easier to hit targets with at longer distances than the rainbow arching 7.62x39.

I've seen ARs outshoot bench guns before, I'm sure many of you have to. What gives?

High quality components, DI driven operating system with less moving parts, caliber is inherently accurate. Someone correct me if I'm wrong.

A big part of the reason is the DI system so many seem to want to get rid of. It may have its negatives, but without a big piston flopping around inside a cylinder attached to your barrel, accuracy is a bit easier to achieve.

Eugene Stoner designed it to be so.

5.56 and DI does it in my opinion.

That plus the way the buffer/recoil system works I think is key.

DI and in-line recoil.

Good aftermarket triggers, good platform for mounting optics.

It's a good caliber from the pure accuracy perspective, and with the amount of aftermarket support that is easily afforded by the highly modular design, it's going to be for a while.

Ive seen a Few AK `s that could hold there own compared to rack grade M4`s shooting M193/M855

But add a Quality SS barrel / FF rail & 52/69/77/80 SMK then the AR is more accurate

aluminum is more rigid than steel most guns are made off. along with what everyone else has said. but against bench guns? no way. not even close. They are accurate for what they are. But they are not magic.

This is a huge one. Aks lock into the reciever. Ar's lock directly to the barrel same as most bolt guns. Also, the tolerances are tight so the luckup is more the same everytime compared to other systems.

Also the DI system. The gas system (especially on an ak) will mess with barrel harmonics.

Which bolt guns?

This. No question.

This. Was wondering how long it would take to get the real answer.


The round is also pretty good for accuracy too for a nearly 50 year old design. Also, good barrel materials due to strong differences in the east/west military mentality.

So does the DI gas system really not play that much into it? Or just not as much as the locking system?

Now how do you argue that one

The gas system helps. Since all the movement of the gas system parts is in line with the axis of the barrel, there is no torque to change the barrel's alignment generated by the gas system. The AK rises not just because of the stock being below the axis of the barrel, but also because of its massive piston, piston rod and carrier moving backward AND above the axis of the barrel.

Well, I learned something new today.

+1.

could be a straight pull bolt action or even a short throw bolt action, it would still lend itself well to accuracy.

the actual design of the action was likely designed around the concept of the bolt/barrel extension.
