Regarding the Zenith 9mm's and 5.56 HK style rifles, can they take HK full auto trigger packs without modification? The trigger packs are $30k+, but I'd be more willing to toss down that kind of money if the less expensive Zeniths could be used.

From what I understand the actual trigger housing has to be specific to the model of HK type rifle/sub you are using. So a Zenith or newer production SP5K would have it's own unique housing cuts versus an older 90 series with the semi-shelf. However a registered trigger pack itself if it's cut for the older 90's style semi-shelf will fit any of them.Quote:

The PTR guns are setup like HK ones and will take a transferable pack without the mods. Same with most other clones.
So I just hit up an indoor range and shot out to 25 yards. 150 rounds of MEN and no malfunctions. My impressions:
- Very little recoil. Follow up shots were easy
- No gas blow back to the face but even with German MEN NATO ammo it was still a smokey affair
- MKE and German HK mags worked fine
- The trigger could be improved but it’s livable. I may send the lower to Zenith for a trigger job
- I am not a fan of the safety/selector or the pistol grip. The AR’s is better. Perhaps I can get a different style lower and grip on HK Parts
- I wish I had an extended handguard so I can get my support hand out farther
- It is a very accurate little carbine. Zenith zeroed the rifle so i did not need to adjust anything.
- The fixed A2 stock is fine with diopter sights but I wish it was collapsible to adjust for LOP
So I think I’ll keep her and ask some more questions here and on HK Pro. Whenever I get time to go to my gun club, I’ll set up some barrels and IDPA targets and compare it to my CMMG Mk9T. I hate to say it, but the ergonomics of the AR beats the MP5 hands down.

However a transferable trigger pack will drop into a Zenith cut trigger housing without issue. The legal issues arise when you need to legally remove the full auto carrier block on the Zenith because it requires that you use an HK wrap around semi-shelf. You can have a full auto bolt carrier block in the receiver itself with the forward take down pin as the Zenith's are imported or an HK wrap around semi-shelf with the carrier block removed. Can't have both a front take down pin and carrier block removed on the same weapon otherwise it's considered an unregistered NFA weapon in and of itself.
I own one, love it, waiting on my SBR stamp. I through a T2 on mine and its a nice gun.

The MKE grip housings have lumps on the bottom of the trigger pocket that match up to cuts on the bottom of the MKE trigger pack, which prevents a non-MKE trigger pack from working in an MKE grip housing. FYI.
I figured as such. I just want a trigger job, that is all. If I want an FBI or Navy style lower, I will have to go for something else.Quote:

If there is Pro for getting the Navy/FBI ambi, its the extended lever called a ESSL.Quote:

HKParts has a new SEF ambi lever but it does not look extended to me.
A Navy SEF housing helps but still not as usable for me like the ambi.

I agree with your assessment of their extended SEF lever. It looks exactly the same as the one my Zenith has.Quote:

I feel like a total HK dork/nerd buying all these parts and playing with them :p
