WE-Tech Metal Threaded Extended Outer Barrel for M9 Series Airsoft Gas Blowback Pistol

"Bought one 5 years ago for my we tech m9 and still have it, borderline idiot proof and does its job perfectly well

"threaded end not removable as was led to believe. still fit well on my KJW M9, just to test that it worked otherwise before i requested to return it, but they just had me keep it and credit me.
