Guide ressort sur roulements V2 [CYMA]

It's a Cyma product, so it's good. Nicely machined, works with all of my pistons. However, it has 4 locking nubs for securing it in the gearbox (ment for a gearbox with a quick-change spring system). No problem; just file down two of them and it should fit into a standard shell.

The CYMA V2 Spring Guide with Bearings is one of those hidden gems in airsoft upgrades – affordable, well-made, and surprisingly effective. I installed it during a full gearbox rebuild, and it’s been flawless ever since.The metal construction is solid, with a clean finish and reinforced base that adds confidence to high-tension builds. The bearings rotate smoothly and help reduce spring torque, preventing stress on your piston and improving overall efficiency.Fits perfectly in standard Version 2 gearboxes (tested in CYMA and G&G shells). No wobble, no extra work needed. Spring sits nicely and compresses smoothly, thanks to the ball bearing system. I noticed smoother spring compression and slightly faster reset after each shot – especially in semi-auto. It may seem like a small part, but it plays a big role in reliability and spring longevity. If you're opening your gearbox, this is a must-have upgrade – especially for high-stress builds. CYMA really nailed the price-to-performance ratio here. Simple, effective, and dependable.
