G&P Troy M7 upgrade with Madbull ultimate hop (is it worth it?)

[Rainbow6]

Afternoon all,

im looking at buying a G&P Troy M7, I recall when I owed one of these a few years back that it was hit and miss re: effective range and there is always a lot of talk about G&P guns out of the box And stuff you have to improve upon

The question is. Is it worth getting the Madbull ultimate hop unit fitted at the same time of buying the M7, I haven't the cash to spend on loads of upgrades etc so am looking at any options and have heard good things about this.

im looking at this upgrade as the place that I'm getting the M7 from has these in stock so can get everything bought and fitted for delivery.

If anyone has any experience of these in their G&P guns then would appreciate and advice etc

cheers
