I'm with you. Old eyes aren't what they used to be.
I run a 4x (F)ACOG on my short barrel.
My 20" has a 12x Simmons. It's a cheap scope, but with the muzzle comp I have, muzzle flip is minimal.
He had this scope on a Stag Arms AR that had a carry handle and the same A-frame front sight as me.
Use it as a carry handle in basic and your DI will break your knuckles
It's original purpose was a shroud to protect the charging handle, which was a trigger-shaped item located inside the hoop.
That version never went into general production and the charging handle was redesigned as a "T" and moved to the rear, but the "hoop" remained, rather than spend the money to retool the upper receiver.
Eventually, the hoop was eliminated on the A4, as it was no advantage for anything, and is a terrible mount for optics, moving the optics too far above the bore axis.
If the hoop is detachable, just remove it and mount your scope to the top of the upper. The front sight post won't even appear in the window on a magnified scope.
