This came off a export exhibit.
The ZH-05 is a weapon that comes closest to fulfilling the the OICW specifications.
Four things plague OICW systems from becoming commonly used.
Weight: Around 5 kg. This weight is not too heavy compared to the 6.1 kg K-11 and 6.8 kg XM-29
Price: Should be much cheaper than previous OICW simply on the merit it is produced in China. Doubtful it'll cost below 3,000 dollars. While cheap compared to the 14,000 dollar K-11 or 25,000 dollar XM-25 it will still be much more expensive than the type 95 or type 03.
Reliability: A core problem with OICWs is the delicate electronic sights. The type 05 looks to have less advanced but more rugged sights.
Deadliness: The 20x28 mm round has doubtful lethality due to it having to in fit electronics as well as explosives. Hopefully miniaturization of electronics has solved most of this problem as well as making a larger round like a 20x32 round.
Worst case scenario: Given to Spec Ops, and other elite infantry like Marines or Airborne.
Best case scenario: Given to one or two soldiers in every squad.
