I guess he's just following in the footsteps of Nolan and Rocksteady and Miller
That gadget in the BvS trailer is the same kind of gadget that Bale Batman used in The Dark Knight: a sticky bomb launcher
The Miller one is a grappling hook. It was meant to play with the reader's expectations. The gun at the end of the trailer isn't like that; it just seemed a little weird. I wasn't particularly keen on the Nolan/Rocksteady armaments myself either.
