Correct AoE on an Aero Cylinder head

[paulwes83]

Hey crew,

Does anyone have a good way to correct AoE with an "Aero" cylinder head? I have a Modify bore up compression set and the cyilnder head is an "Aero" design. (I'm using it on a 590mm inner barrel, so I'll need the extra air volume from what I've been told.) It's not the same as the "Silent" cylinder head with an o-ring along the outer rim of the cylinder head. The entire inner face has a thin rubber layer on it.

I'm not sure if adding a "Silent" style o-ring would be wise since it would prevent the "Aero" style piston head from mating properly against the back of the "Aero" cylinder head.

I won't be running anything more than an M140 spring so the stresses shouldn't be too bad from the impact and the piston head is aluminum.

Does anyone have any experience with this kind of set up or any educated suggestions?

The 2 options I see are either adding shims between the piston and piston head to correct AoE, or making a home made sorbo pad and fitting it to the Aero cylinder head...how I'd do that I have no idea ATM.

Thanks to anyone who can help

You can use shims but you'd lose the benefit of shock absorption of the sorbo. I would just modify a normal bore-up sorbo by enlarging the hole. The silent type sorbo will probably still work, but you can probably maximize the size of the material by doing it yourself.

If you're lucky enough, you might be able to convince Scatterplot to cut a custom one for you.

Thanks man, turns out Scatterplot has some sorbos labeled as "bore up" on Airsplat that I'll try ordering. Hopefully they work well as is, but I think you're right in that being the way to go. Even though it's meant more as a semi-auto gearbox, with full auto still available the shock absorption will be really beneficial.

Thanks again!
