510 Hercules suppose to have such a restrictive airflow?

Hey guys, just moved up from the Omicron v4 to the new Hercules. I noticed it has a super restricted airflow. Is it suppose to be like that by any chance? It's like 10x more restrictive then my Omicron v4.

Everything is completely clean, I boiled it, etc. Did I just reassemble it wrong or is it really hard to pull through the Hercules unit?
