Description
The MKE Trigger is the factory-correct fire control piece for Zenith's roller-delayed blowback lineup, and it's the same trigger that ships standard on their guns straight from the box. If you've got an MP5-style pistol or rifle running an MKE trigger pack and the original has seen a lot of range time, this is the drop-in match to bring things back to spec.
Zenith builds these on the original German tooling and dies, working from the factory technical data package rather than reverse-engineered measurements off another gun. That matters with a part like this, because trigger geometry needs to be right for a clean, consistent break and dependable reset. This is a genuine MKE component manufactured in Turkey, carrying Item # A7-714, so you're getting the real deal instead of an aftermarket approximation.
Where the MKE Trigger Fits
This trigger is compatible with Zenith's semi-auto and SEF trigger groups across the roller-delayed family, including the popular Z-5 series pistols like the Z-5RS and Z-5P. Those guns run a delayed roller-lock action licensed from the H&K MP5 pattern, and the trigger pack internals follow that same proven design. Whether you're doing a full rebuild or swapping in fresh parts one at a time, this keeps your fire control matched to the platform.
Getting the MKE Trigger Installed
Trigger pack work on roller-delayed guns rewards a careful hand. Zenith recommends that parts like this go in by a qualified gunsmith or trained armorer, since proper fitment and function checks are part of doing the job right. If you're an experienced builder who knows your way around an MP5-pattern trigger group, it's a straightforward swap, but there's no shame in handing it to someone who lives in these guns all day.
Keep a good firearm lubricant on the moving parts of your trigger pack and this piece will do its job quietly for a long time.

Frequently Asked Questions
What guns does the MKE trigger fit?
It's designed for Zenith's roller-delayed blowback firearms and works with their semi-auto and SEF trigger groups. That covers the MP5-pattern lineup like the Z-5RS and Z-5P pistols. It comes standard on Zenith roller-delayed guns, so it's the factory-correct replacement.
Is the MKE trigger a genuine factory part?
Yes. This is a genuine MKE replacement part manufactured in Turkey by MKE and carries Item # A7-714. Zenith builds their roller-delayed components on original German tooling using the factory technical data package, so you're getting a true-to-spec piece rather than an aftermarket copy.
Can I install the MKE trigger myself?
If you're comfortable working inside an MP5-pattern trigger group, it's a manageable swap. That said, Zenith recommends installation by a qualified gunsmith or trained armorer to make sure fitment and function checks are done correctly. Proper trigger geometry is what gives you a clean break and reliable reset.
Will this trigger improve how my gun shoots?
This is a factory-spec replacement, so its job is to restore your fire control to how the gun ran when it left the factory rather than to add an aftermarket pull weight or upgrade. If your original trigger has worn from heavy use, dropping in a fresh MKE unit brings the feel back to spec.
