My first rifle experience was learning the FN the army way.
"Left hand operated" was a brilliant concept to me as a right handed guy.
The right hand stayed put on the trigger and grip and the left hand did what ever was needed.
There is no perfect rifle and the concept of amnidextruous is mere admission to it.
Stag is probably the only AR builder who address the pronlem by offering mirror image ARs in left hand mode.
Yet, even then they still have the centered cocking handle problem.
That's right, I said problem.
You still have to poull your face away to #### the thing.
The closest thing that I have found to my FMC1 perfection is,,,wait for it,,,, the Robinson XCR.
Left hand charging handle and ambi everything else.
Latest rifle to impress me has been the WK180C with the option of putting the cocking handle on what side you want.
There are a few other rifles with the changing the side option.
Some have stuck with the true ambi concept of the original AR10 like the T97, but folks don't want to hear things like that about the little ol' T97. For leftoes ejection ports matter. My advise is to grow a mustache to hide the hot casing scars.
I like charging handles on the side of the off hand.
