CQB Master CNC MP9 MPX QD Flash Hider - 14mm Negative

"This item makes your MP9 look so cool it will look like a MP9 times ten!

"NOT MEANT FOR MP9!!!!!

Solid material, but not meant for MP9 like other reviews and comments have stated.

This will fit fine on 14mm negative threads fine and has a set screw to secure it to the threads.

"this is NOT meant to be a way to convert your KMP9 to a standard threading, it instead is intended for an AEG to convert it to QD.
buy the 30$ g&g barrel thread for the kmp9
