Angel Custom Tunable Spring Guide for Cybergun FNX45 Airsoft Gas Blowback Pistols

"Amazing spring guide that's added the kick and return speed I've wanted for my fnx-45. Was super easy to install and seems to be holding out super well, only time will tell!

Def recommend.

"The spring guide drops in quite nicely but it does not have the little dimple where the slide lock is gonna fit. Still works fine, but it is not 100% fitment.
Otherwise it makes the slide super snappy!

The hammer spring was a bi*** to install but here`s a tip:
Only losen the spring and after installation, pry it back into place with some pliers. They don`t sell all the other parts that you are gonna destroy opening the whole case.
Or: just dont replace it..

But the spring guide is a go 👍

"This review focuses mainly on the guide rod.
For starters, the build quality on this thing is excellent, with a nicely tensioned spring and clean machining. It's also very strong when you can get it to work, which is about where the praise for this ends. This guide rod fundamentally failed to do what I had purchased it for, which was for a 130% guide rod, as with all the spacers in to make it that percentage, the spring doesn't give the slide enough travel room enough to catch on the slide lock, only going about half way across the catch. It doesn't work at all until you remove all the spacers via the unscrewing of a tiny Allen screw under the spacers on the rod. After installation, the round bit that interfaces with the hop up unit is a bit too big, which causes the take down lever to slightly angle upwards when the slide locks back do to it rubbing against it.
TL;DR
Pros:
Build Quality

Cons:
Literally doesn't work as advertised
Pain to adjust
Built too large to fit oem
