Good morning. I am interested in buying the Diamondback Firearms DB15 5.56x45 NATO 16" Black, M-LOK Handguard, 30+1 rifle. The question is multi-caliber as it is written in the lower. Thank you.

Hi Jose and welcome. Yes Sir it is. You can use the lower for other compatible caliber uppers no issue. Cheers and stay safe!

Good morning Jose, the DB15 5.56 NATO is chambered for 5.56 NATO, so it will fire both 5.56 and .223
The Multi Cal printed on the lower just means this lower can be used with other calibers, if mated with the correct upper. 
Stay safe & have a great day!
