B&T QD-CQB SMG/PDW suppressor, cal. 9x19mm

As it is a little more than 50 mm shorter compared to the standard QD suppressor, the CQB is a good alternative when, for example, for the use within a building the system gun/suppressor should be more compact.
Thanks to it 3-lug lock it can be mounted/dismounted on all weapons with 3-lug lock on the barrel (MP5, MP5K, APC9, P26, KH9) in a matter of seconds.
