This is my new coke bottle hybrid.When it was combustion it was pathetic-quiet, little chamber flashes, the battry didn't do any damage.The butane was very slow burning because the ignition is far from the senter.Now as a hybrid it is LOUD, makes damage like a pneumatic and the flashes are great.
And I forgot to say that the recoil is great too.

I suppose you use something around a 2X mix.
What do you use for burst disks and what's the ignition?

I use a lot more.May be around 4X.The bottle was 500ml and I made it 200ml to be stronger.The burst discs are from some old plasic bag.

You are right.But I don't pomp the air.It comes from a pepsi bottle under presure.

It functions just the same, only you don't have as much control of the ammount of fuel and air you're using.

This is 1.8mm steel and an old battery.Looks like hybrid rules for sniper.
