CircularSquare88 Posted December 6, 2021 Report Share Posted December 6, 2021 All, I am looking for an HK SP5k SPEC ONLY 4-position lower for my host. I had no idea that I would not be able to use my other 4 position with my sear in it but it is what it is. Let me know what you have and how much. respectfully Quote Link to comment Share on other sites More sharing options...
