hi everyone i just bought a piranah bl vf g3 and would like some advice on what parts i should buy to upgrade it. loaders, expansion chambers, etc... any help would be appreciated.
The Piranha is a very upgradeable marker.
A new barrel may be interesting, as will an electronic hopper.
Also, if you are planning to do any internal upgrades, try one of them Shocktech bolts. That way you'll never have to replace an o-ring on your bolt ever again.
If possible, get both, but if you're looking to buy just one of those two, go for the reg. It'll give you better consistency, and should you want to get a new marker, it can be used on that too.
