For: CYMA Metal Hop Up for AKProduct Information:
This hopup unit is great for the price! extremely easy install. It feels really sturdy and durable. I did notice an increase in accuracy but im not sure if was the hopup bucking i ordered or a mixture of this AND the bucking.
It is Metal
Perfect fit and super easy instalation
The only con is that it didnt come with the screws you need to put it in.... so i simply used the original ones. lol
