E and L Gen 2 Gearbox

Yup that's why.

The guide-spring-piston system needs to have a little bit of tension at all times.

In v2 boxes it's not a really big issue since the spring guide is kept in place by the buffer tube screw, but in an AK the guide isn't held by anything but spring pressure..

Yep, especially with QD spring guides.

But the amount of damage it did to the GB shell was quite eye-opening. I wonder how many other E&L users are having the same issue without them realising, gradually filling their GB with metal confetti.

Speaking of which, the ZCI QD Guide I ordered was a straight drop-in fit. Looks slightly misaligned in this picture, but that's the crappy stock Specna Edge spring I had lying around that I used for testing, brand new but kinked in the middle. I will be buying something of better quality shortly.

Last time I took mine apart, it was fine, albeit the spring is kinda shorter than usual (because the guys @gunfire nicked it off to stay below 1J)

Will check again as soon as my parts arrive, I wanted to replace the spring anyway as it's a bit on the low side (around 0.75J)..

i've not had any issues with disintegrating spring guides on the e&l's, but it's good to know the ZCI is a drop-in replacement if i ever do.

There are certain after market attempts to rectify this. One example is retro arms have a screw that attaches. Problem is it can make the gearbox too long to fit in certain bodies. The one in the photos fits in a LCT body but won't fit a King Arms body.
