"amazing piston head. I have it in my main rifle, shot about 20k bbs. Still running strong.

"This is a great piston head. I currently run three of them. One in my M14 EBR build, one in my SCAR-L, and one in my brother's M4. It's an extremely lightweight piston head, so it doesn't slow down the ROF at all. The compression is fantastic as my fps only fluctuates about +/- 3fps per shot. Will definitely be buying more and installing them in more guns!

"This piston head is very lightweight, so it won't slow down RoF at all. The eight ports allow for an efficient expansion of the o-ring. The material that it is made of has minimal flex and is stronger than other polycarbonate-made things.

"nice and lightweight nothing much to say wouldn't run this any higher than m120 i have seen these shatter before and keep it under 30 bbs a second to be safe
