Our friends at The Firearm Blog have an interesting post on China's development of an OICW-type weapon with both a small arms round and built-in airburst capability.
The so-called "Type 05 Strategy Rifle" or ZH-05 is a 5.8 standard carbine with a bullpup 20mm airburst round launcher embedded in the frame.
Some commenters argue that this is a path to nowhere, like the US Army's XM-29 program. But others are saying that Chinese manufacturing could bleed out the bad parts of the XM-29 and its ilk.
Weight: Around 5 kg. This weight is not too heavy compared to the 6.1 kg K-11 and 6.8 kg XM-29But judging from some conversations I've overheard about the lack of real capability of the SKorean K-11, I'm not sure the ZH-05 path is an economical and effective one to go down.
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.
