ZCI V2/V3 Integration Cylinder Head

Great quality, great airseal. They come in random color, mine came red. I love the pad on this cylinder head, it's a little softer and a bit thicker than a normal/stock pad. In a customers gun, this actually over-corrected the AOE. And I actually had to shave the pad down a bit. (This will depend on your piston head though). Very happy with this product so far. 9/10
