This the fairly modern Chinese CS/LS2 – the 9mm Parabellum export model of the 5.8mm QCW-05 submachine gun. It takes most of its design cues form the QBZ-95 rifle, as you can see form the grip layout. It is a bullpup, with a right-ride ejection port that cannot be swapped. It is a bullpup style design, with the magazine behind the trigger, and it fires from an open bolt with both semiautomatic and full auto selector options.
The receiver is made of aluminum, contributing to a quite light gun. The bolt is also relatively light, resulting in a high cyclic rate and more felt recoil than many 9mm SMGs. The bolt is slamming into the rear of the receiver on each shot, which causes a lot of movement in the gun while shooting. The iron sights are a removable option on an integral pica tinny rail, which is a good thing – they are awful. The same minuscule rear aperture that the QBZ rifle has. The suppressor is not particularly efficient.
I have no prejudice against Chinese small arms – Chinese AKs were/are extremely well made. But this modern bullpup family is really pretty mediocre in all its forms.
Many thanks to Movie Armaments Group in Toronto for the opportunity to showcase their AR-10 rifles for you! Check them out on Instagram to see many of the guns in their extensive collection:

At Forgotten Weapons I think the most interesting guns out there are the most obscure ones. I try to search out experimental and prototype weapons and show you how they work, in addition to more conventional guns that you may not have heard of before. You’re much more likely to find a video on the Cei Rigotti or Webley-Fosbery here than an AR or Glock. So, do you want to learn about something new today? Then stick around!
