hop-up. Prowin cnc Vs ascu

[liam88]

I currently have the pro win cnc hop unit in my m4 which is fantastic. But I also have an ascu v2 fitted so quite fancy the bolt lock feature you get with there new hop unit.

Question is how does it compare to the pro win. I dont want to downgrade as such just to have a bolt lock feature. How easy is the installation ie the wiring ?

Discuss..
