Poseidon ZERO1 Anti-Ice Nozzle for WE-Tech Gas Blowback Airsoft Rifles
(Model: WE-Tech SCAR)

"I liked the idea of the anti icing nozzle. However, I see no difference in gas efficiency. I ran approximately 200 bbs through the gun after installing this unit. During that time it functioned just fine. The following weekend I fielded the gun with this unit in it. With 15 minutes of the first game of the day my gun malfunctioned. I field stripped my MK!7 and noticed the end of the rocket spring had unraveled and was sticking out the end of the nozzle!! Upon closer inspection of the spring it was clear to me that the spring was not heat treated as it did not return to shape. additionally the cone shaped design of the rocket valve spring is weak and unstable. Most rocket valve springs are straight not coned. This provides a very stable based for the valve. I have since replaced the ice pick rocket valve with another npas and it functions just fine.
for as much as this costs I would have expected the same quality as the poseidon barrel I purchased for this same gun. So now i just have a spare nozzle nothing special here. Perhaps this is the reason they have a spring repair kit (that is also out of stock), they expect it to fail.

"I disregarded the previous review because I saw youtube videos of it working.It looked and felt even sturdier than the angel custom or we tech nozzle so I never tested it until I needed it .With full gas,my 416 was shooting 485 fps then it settled down to the 390s.When the magazine ran dry I noticed something white on top of it.Turns out the back end of the nozzle exploded and that was the white plastic oring. Even the we tech nozzle lasted longer than one magazine.I am happy I found this out now and not during a game.
