. 30cal. Raw hm1000x question

Hi , 

I ordered my hm1000x lrt with the polygonal Barrel i was under the impression that the polygonal Barrel isn't choked. Today i watched a YouTube video that was testing slugs and he made it a point to mention that the polygon a barrel is choked and we'll have a tough time shooting slugs. Can anyone tell me if this Barrel is choked or not? Thanks in advance
