Gray fox it is about maxed out in that pick. For me it sits down around my jaw for proper sight picture thru the red dot. Now my mueller sight sits up alot higher than a burris so take that into consideration. I plan on cutting a mouse pad or something to put on the check peice just in case but when I was patterning it this yr I never really has a prob with it hitting my face but you know the awkward positions those turkeys can get us in so better safe than sorry
