KJW Reinforced Loading Nozzle for Airsoft Gas Blowback Pistols (Type: 605 Series)

"Fits Tokyo marui hi-capa's
It comes with a plastic rocket valve inside that has rubber to seal on it. It won't break and fully seals. It has a metal pin to hold it in rather the the typical screw. It also aligns 4.3 slides better making the front part of thr slide flush with the lower. Better then the stock tm nozzle, it's stronger for sure.

"It fits the CowCow Tech BBU, however mine did not come with a plastic rocket valve like another reviewer seemed to indicate, so I can't test it. However the build quality does feel like quality plastic.

"Just bought this for my stock TM 4.3 (Xtreme.45) as my stock nozzle broke. Unfortunately, the piece does not fit with my stock blowback housing. It's too large.
