From the info and looking at that picture, I think the remote goes behind that lens thing on top. You can see the little lever just above his thumb which presumably hits the B-trigger.
And it seems to claim "light bending tech" so that you can point the gun directly rather than aiming the remote off-screen.... I can only guess it's kind of like a binocular lens that you can adjust depending on your screen size.
Edit... no wait, I am quite wrong. My first 2 lines in fact describe a button for his jacket 
and seeing the other pictres shows the remote position, so the light bending stuff is just about not having the remote pointing directly forward.
