Should i ?

I am thinking of getting nerf gun for my boyfriend. First of all should I get it for him? He's 21. He likes games like CODM and BGMI. If yes then how should I ask him indirectly if he likes nerf guns? Earlier I have gifted him hot wheels tho n he probably liked it. Edit: better gift suggestions are appreciated (should be good n unique tho not regular cologne, shoes, watch, clothes type shi) also thoda budget mai btana apna pett kaat ke ghar valo ki allowance se hi Dena hai am 18 tho.
