I have the US made ambi pack from HKParts. Seems like $400 is a high price to pay for the ability to select Fire/Safe on presentation, but it is what it is. The pack works on both my Zeniths and I don't see why it wouldn't work for you. The stock SEF trigger was better with respect to smoothness and feel.
The HKParts US flat trigger helps and is relatively cheap. Its a little more involved than an AR trigger swap but have a few beers and it will all fall together!
