Which 4 Position Housing for SP5K PDW?

[esh21167]

Here are two housing from HK Parts.

One just says MP5K for semi auto shelf, but the picture shows that it's not cut out for the shelf: https://hkparts.net/product/mp5k-4-position-clipped-pinned-trigger-housing-p404.htm

The other says SP5K specific, but shows no picture of the shelf area: https://hkparts.net/product/hk-sp5k-spec-only-4-position-clipped-pinned-trigger-housing-p17923.htm

Which one is plug-and-play for a new SP5K PDW? I'm guessing the SP5K specific one? Thanks.

If you have SP5k you will want to be sure to get the one that says SP5k Spec . Fit will be off if you don't.
