Mk 262 is good ammo, if you do your part. But, alas there is no wonder bullet.
As for the AK. It all depends on who made yours. Most all domestically produced AK's cannot be compared to the real deal AK's for a variety of reasons. Number one being the mods to the FCG.
Wouldn't it be a pain in the butt to align the gas hole in the barrel of the AR? The barrel extension is threaded on. This sets the timing of the rifling at the gas hole location. I guess you would need to have many barrel extensions to get one that is perfect, and even then you would probably be sacrificing perfect headspacing for having your hole in the groove.
Then why bring it up?The AK-74 was redesigned specifically because gas port location and shape caused accuracy to fall below Soviet requirements.We know this. This thread was asking if there is a specification for it, and if not, what makes the AR different.
dull bits and incorrect feeds/speeds will raise a burr on the edge of the hole. It's an area that is hard to access with convention deburring methods. Otherwise, removing material that will erode away eventually seems, strange.
Currently, wracking my brain to come up with a test to determine if gas port location affects accuracy.
Read an interesting article once discussing location of gas port versus land/groove, lots of tests and pics, just can't remember where I saw it :(. Anyway, conclusion was, it didn't seem to matter, aside from the holes that were 1/2 in the land and 1/2 in the groove seemed to exhibit less erosion after extended use. :confused:
