While new it was identified as an early build so several test shots then preventative check of internal screws which were cleaned and thread lock applied to avoid known issues.

Sounds and feels good, so pleasant to shoot, I will run some comparisons with .177 once I have a couple hundred pellets through.

Eight screws, small key and polymer bush removes the add-ons to reveal a basic gas ram break barrel.
The large black sleeves each end of the chamber slide inside the aluminum tube.
The sliding components have 0.5mm clearance.
The mechanism moves 20mm during each operation.
The moving parts of the anti-recoil are not lubricated.

I recommend checking the reviews by The Airgun Detective which identify some early manufacturing problems.

If purchasing it is important to confirm yours is an updated model or improvements were undertaken.

I queried Norica and received the following response from the Technical Support Team.

The Omnia ZRS carbine has undergone some updates.
These studs have currently been replaced. It requires the following spare parts:

Ref. 20130103
Ref. 20130113 x 2 units

Front screws 20130113 and rear screw 201301001 have been known to come loose, if they contact the aluminum housing they will cause damage and possibly seize preventing disassembly. An earlier issue with my .177 ZRS was resolved under warranty but I am not taking any chances with the 22.

Along with thread locker I have deformed the plastic bush with a solder gun so they cannot unscrew inadvertently.

Can the ZRS be more than a backyard plinker.

Clearances tightened with aluminum tape.
Front alone was not very successful.
Tape applied to both front and rear seems to improve accuracy especially when using scope.

Removed the obvious free-play but still slides freely.
Checked for wear after 100 shots and no issues.

Still working on the .22 

The ZRS .177 was also modified and tested indoors.
Bench-rest 25 yards with 3-12x40 scope.
Four shot 23.16mm OD group.
It is more consistent but there are better results elsewhere.
I was hoping for 12mm.
