I could stat the grunt out. I'd consider him a Professional Rating 1 Lieutenant, as it'd be an uncommon opponent that requires a lot of skill and nuyen compares to your average ganger.

His role would be to just find guns and commlinks and brick them, not to go toe to toe with another hacker. Still a ganger though, so he should be ready to shoot somebody up in a moment's notice, but the gun is a cheaper model than the usual one gangers have. While his dice pool for Cybercombat is much higher than most dice pools for gangers, it's still significantly lower than what a PC will have and is necessary due to how the matrix works (dice pools just need to be higher to get the basic stuff done).
This is for the more small time gangs of course, where most members have a metalink and are incredibly poor. More "middle class" gangs, like go-gangs and other ones where the members are better equipped would probably have a "sub-hacker" with up to R5 gear, probably. I could see a go-gang having someone like this, both for fucking other people's vehicles and to be able to fight back it someone tries to take their bikes from them via the matrix. At that level it'd probably have a modification, too. Maybe like a hardwired Vectored Signal Filter for NR in addition to the amount from the data jacks they'd have.
Once it gets up to like, Professional Rating 3 though, it would probably make more sense for a full-on decker with one of the cheaper decks, like the Little Hornet.
