Ver 3 Cylinder Heads for AUG
 

I just purchased a Prometheus Aero ver 3 piston head for my TM AUG, but I discovered that there's a separate one for G36/AUG.

Does anyone know how this will affect my performance(velocity or shot-to-shot consistency change)?

you will get low velocity.

the G36/AUG cylinder head has a nozzle base. With the one that you have the nozzle won't be long enough to get a good seal within the nozzle and so, air pressure will be lost.

Thanks ILLusion.
