Howdy, have the RRA EOP varmint[or varminteer..too lazy to look] w/24", 1:12 barrel and I love it.
I'm just an old "trigger puller" but after messing with scopes mounted on carry-handles for years, thought I'd died and gone to heaven.
High rings are probably fine but EOP looks way better, IMHO. Probably some versatility issues I'm not aware of.
