For: KWA Threaded Barrel Adapter for Umarex H&K MP7 (12-14mm)
Does what it is intended to do. I got this so I could use a tracer mock silencer. Be ready to try to get the stock flash hider off, which is glued on and requires a lot of work. There are many solutions for this online. I chose complete disassembly and use of a heat gun to loosen the glue.
Works great. I can now attach many of my existing flash hiders, which adds volumes to the aesthetics of the MP7.
Requires a lot of extra work to take off flash hider. Consult a professional if you're not confident.
