Hopup rubber without a bump

[flack]

Hello there!

I'm not even sure if it exists or not but i'm looking for a hopup rubber without the bump inside. I have been searching for a while without success.

(this is a GBBr rubber but i'm looking for an AEG one, but you can clearly see the bump i'm talking about inside)



anyone ever heard of one existing?

thx

I put a Prometheus soft rubber in my gun a few weeks ago and they do have the bump. I heard that the Guarder clear rubbers dont have them but that I do not know first hand.

Guarder Clears have a bump

If you buy a Well l96, the stock rubber doesn't have one. At least mine didn't. So they exist.

carefully turn the bump inside out and put it over a rod that's an even tight fit (AEG rubbers will easily go over a regular inner barrel).

Then use a sharp exacto/hobby knife (the sharper the better) and trim the bump off. Don't try to take it all off...you risk putting a divot in the rubber. Then use fine sandpaper to buff it even. 400-600 grit works fine.

Practice on a old/spare rubber...then go for it.

This is exactly what I did except for the sandpaper, never thought about sanding rubber! Ill give it a try, it will probably give the result of a flat rubber!

Thanks everyone!

EDIT: btw G&G stock, Garder Clear, Systema, firefly and prometheus rubbers have a bump!
