I have a Gen 2 FJR and I am considering purchasing the Rifle + 5" (I wish they had a +4) because I am 6'2". Anyway, I really like the look of the shield from their photos on the website, but I am totally confused on what the Angle Optimizer is? This attachment looks HUGE on the website and it says that this must be installed with the shield. I cant imagine that big thing looking good on the FJR, but maybe I am missing something because I cant see it on the installed photos. Link here...Rifle Gen 2 shield Any clairfication appreciated.
