1. Straight brass case.
a. Brass cases are MUCH more expensive then steel/aluminum cases.
b. Straight cases are inherently harder to feed/extract and suffer from ramp stoppages.
c. Straight cases are naturally prone to rupturing if the chamber is contaminated even with the slights of debris, which was a severe problem with early M16 which did not have full chrome lining.
The 5.56 is not a Straight case, it is a necked down case.
I suggest that you change your first post and indicate the case body and not the whole case.
Now then I'll put up or shut up. My AR against your AK. 100yds to 1000yds and everything in between. We'll use the standard USPSA targets.
No, no, now your changing calibers.
Why yes I do.

Got a night sight?
After I get an AR-10 then I'll get the high end toys.
I gotta tell you an AR is simple to work on and cleaning is no problem, push one pin out and pull the charging handle and bolt. A few dots of mil-tec and away you go.
