A&K M60E4 HPA help
 

Hello and merry Christmas fellow plastic slingers. I need some help. I have an A&K M60E4 that I?m looking to HPA. I?ve never done this before, but I?m thinking I wanna make mine mountable and HPA. The pro I?m having is that I don?t know what engine to use. I?m not looking to brake the bank, but still want good performance. Any tips, suggestions or tricks are welcome.

Any of them are going to work well enough but if you want it to be extra fun, the Daytona engine adds that recoil element

If you aren't looking to break the bank, then you shouldn't be using an mg, let alone an hpa one.
But that aside, Daytona is costly, offers recoil and is a pig when it comes to air usage.
P*/wolverine have a few options available from a full mechbox replacement, to a cylinder replacement and is a lot more air efficient as well as able to be much more finely tuned.
