Century AP5-M : MKE lower swap to HK SEF Navy lower

Just a quick video I forgot to upload a while back. I recently got an AP5M and wanted to swap the lowers cause I hated the thumb rest/finger grooves. Picked up the HK SEF Navy lower from HKparts for like $75 or so. Worth it. Also, eform 1 complete with mailing prints in 21 days! 🫡

Did you have to do any fitting to get all 3 push pins to to seat!

So, the trigger pack is serialized and not the lower , unlike an ar?

No the “upper” is.

Love my AP5-M, but Century customer support sucks ass.

How does the trigger feel? I tried it on mine and for some reason made the trigger pull heavy and gritty.

Trigger is fine on mine. You sure it’s all lined up and not in a bind?
