Guarder Lightweight Nozzle Housing for HI-CAPA 5.1/4.3 Airsoft GBB Pistols

"I was kind of sketched out buying this with no real in depth reviews that I could find. I was actually surprised, the fit is absolutely perfect on a stock 4.3 slide. The included nozzle spring I estimate about 140%- 150% and feeds amazing. This paired with a stock TM nozzle and piston head will create almost no recoil on a stock slide. I haven't tested fps variance yet but I will add it later compared to the original TM which had a variance of -1 fps

"This housing is light but the KJW nozzle and APS nozzle don't fit, very tight even without the diaphram. My original nozzle is nearly identical, looking at the pictures of the Guarder nozzle and valve, yet it doesn't quite fit.
I presume you need to order the other Guarder parts to match for proper operation.
It did fit in a TM slide just fine.
It should be sold as a set, being that it is not a universal fit with other brand components.
