“I used this with a pink maple leaf bucking and a prommy 6.03mm tightbore in a sr25 kythera build built from an a&k sr25. I had many issues. For starters, the hop wheel was too big and was rubbing against the receiver to the point where I needed to take the gun down to adjust the hop. Also, the tolerances are total garbage. I had a good millimeter or two of play in the barrel where I can freely rotate and wiggle the barrel when all equipment was installed. I was getting double feeds a lot. Lastly, I was getting inconsistent shots. Overall, avoid this hopup and get either a maxx or a ProWin.”
