Thanks to it 3-lug lock it can be mounted/dismounted on all weapons with MP5/APC9 type 3-lug lock on the barrel in a matter of seconds, even faster than the normal QD suppressor. To mount the SQD™ suppressor it must be slid on the barrel, where it locks automaticly in place thank to the innovative SQD™ mount. To release the suppressor, only one knob has to be pressed in order to dismount it.
The SQD™ suppressor does not work with the P26 and the KH9.
