Hello all,

I just bought a PTR 9KT, I'm wanting to put at the very least an extended left lever but ideally an ambi selector.

Does anyone know for sure what selector lever(s) to get to do this?

The Magpul one is the easiest option, it's extended and can be ambi.

Thank you! Was wondering if that would work, seems like the easy button for this for sure.

It's an SEF type housing/trigger pack, which is what the Magpul one is made for.

You cannot use the HK-style ambi safety that comes on their pictogram housings, those use a totally different bottom end and are not cross compatible with SEF ones.

Just make sure whatever you use, it says it's "SEF-housing compatible" or something to that effect.

HKParts has a set that works with the SEF contoured  housing
