RUGER AR 556 free float guard install

Hey guys new to the AR platform and to this forum thanks for having me.I want to put a 15 inch free float on my AR. Will I run into any issues because of the front sight/gas block. I seen a few videos on this and it looks like the roll pins that secure the gas block/sight to the barrel leave divets in the barrel will this give me problems when I try to install a low pro gas block.

You shouldn’t have any issues the divit in the barrel won’t cause any problems. Be sure and get a low pro gas block and look at the site sponsors like Apoc Armory for your rail and block.
