The HD66 is a Chinese pistol accessory which allows an operator to fire at targets around a corner without being exposed to return fire.
The HD66 was first introduced in May 2009 at the 4th China Police Expo held in Beijing. It is co-developed by Chongqing Changfeng Machinery Co Ltd and Shanghai Sea Shield Technologies Company.
According to Qing Shanseng, chief designer of the HD-66 and CF-06, both systems are indigenous and were not done based on the CornerShot.
The HD66 weapon system is comparable to the better known CornerShot system.
Developed and unveiled alongside the HD-66.
Developed by the China Ordnance Industry Research Institute in 2005 in an attempt to do a similar system to the Israeli-made Cornershot.
The CS/LW9 has a handle at the bottom that can be used to turn the LW9 to the left or right. Aside from the QSZ-92, the LW9 may also be fitted with the Norinco NP22/34, Chinese-produced SIG Sauer P226 and P228 pistols.
