My brother in law's birthday is coming up and I need some gift ideas. He's in the marine reserves, big into working out, fights in MMA, only thing lacking to be the ultimate man's man is he's not huge into the outdoor side of things. He does a little bow hunting but doesn't fish or do much else. Budget is $100, we got him a Spyderco knife last year which he was happy with. Not sure what to do this year, any ideas?

Tldr, need a gift for bro-in law whose in the marine reserves and fights in mma. Budget is $100.

Glock 19.

Maybe a nice flashlight?
