    Will need modification to fit Century/AP-5.

    Posted by Quint Young on 5th Dec 2023

    While other HK original MP5K trigger housings have always fit my AP5-P perfectly, this is not a drop in fit. I'm pretty sure the SEF Navy packs used here weren't ever a factory MP5K trigger pack. The second hole was drilled by HK parts. This combination of products is a good choice if you want to get a Binary pack with the ejector already installed and an MP5K SEF-Navy grip pack at the same time. This is NOT an advisable option though if you are hoping to personally avoid any assembly or hand-fitting. Do not expect these packs to be "drop-in" or "plug and play" with push pin lowers. You will likely STILL need to do some work to actually get it to fit and work correctly.
