Corrosive ammo?

I just built my first ar, and Im planning on going shoot it on my grandparents property tomorrow. My question is I’m going to buy about 60 rounds of ammunition from academy to shoot and I don’t have the bore snake or any cleaning kit to clean my rifle after the shoot. Will I be ok?

I have a 1:7 twist chrome lined barrel.

Yes But I would go to wally world and get a Kit ,they have some as low as 5 bucks, at least get some break free CLP and spray down the barrel until you can clean it right
