I have owned a large number of AR-R-15’s and semi-auto variations of the AK. I have never had a jam with either tho I haven’t fired a huge number of rounds and also keep all my guns clean.
One can get an impression of a gun, some just seem like they will eventually jam and others seem to run like a sewing machine. The AR-15 is one of those sewing machine guns.
In my experience, the AK is more accurate than many claim but still not even close to the AR’s. The AR-15 is often more accurate than a bolt action. I have no idea why but they are.
I would personally prefer the AR-15 H-Bar over any other gun except maybe the FAL. Also really like the HK-91.
AK-47-—it’s a little bit too heavy though...
I shot the M-16 at 500 yards and couldn’t read the target numbers, had a spotter. Put 8 rounds in a 10 inch circle. As for jamming, it don’t handle the dirt very well. Have to keep the ejection port closed.
My theory on why the AR seems so accurate is two fold: amazingly precise sights that are amazingly easy for the eyes to use. And recoil. The super soft recoil makes it effortless to shoot and shoot and shoot. There is nothing that compares.
Barrel design.
