"Ok so most people above say it doesn't come with the rubber part on the front. This is not true mine came with it. I paired mine with a high quality cylinder and tested my air seal. Also paired with a vfc air nozzle the air seal was spectacular. It feels a bit light and almost like plastic but thats cnc for you. 5/5 i would reccomend it.

"this is not a bad cylinder head at all. its actually really good when it comes to keeping an air seal. the dual o-ring really does its job. Other reviews have said that the rubber seal on the front of the cylinder head never came on theirs. Mine came with it and it does help to preserve the front of the gearbox. while installing other parts i did notice that the buffer pad on the back is very loosely glued on. It did fall off. so beware of that. Overall this product is not bad and i would recommend it to all, just re-glue the buffer pad and no doubt will you be shooting at least 35+ fps.

"Even thou i emailed Evike to make sure they send me one that was exactly as the picture, pointing out the fact that one review said it came without the front rubber part... mine still came without the front rubber part.
The rubber wasn't missing, there was simply no room for the rubber to ever have been there. Just a flat aluminium surface.
