Slong Airsoft CNC Aluminum 14mm Negative Threaded Adapter for KSC/KWA MP9 Gas Blowback Airsoft SMG (Color: Gold)

"Exactly as advertised. I bought a brand new Kmp9 and did absolutely nothing to it. Bought this adapter and it screwed right on tightened the two hex key screws in the side and boom done. Super easy install and it works without any modification to your gun or the adapter. Do Not buy the G&G one! It’s more expensive and requires extensive modification to actually work. This one is 10x better. I added a pretty heavy rifle tracer and no wobble. Only disappointed that it didn’t come in black. But I can get over it. Overall great product and would buy again.
