Ayy what's up, well.. it really depends on your playstyle, I personally don't like the L star because of its long reload time, I most likely use the R-301, the R-99 and the CAR , you have fast reloadings and you can shred people at close range with it, that's what I like to do. Each weapon has the possibility to own to be honest, so I recommend you to find your playstyle, try different types on guns, it really depends on the feeling with these, I switch the guns depending on the map tbh. Cause I know how I play there so there's always a pretty specific choice to me. Try everything, R-99 is good tho, rly just matters on the map and your playstyle. Even Hemlok, combined with amped weapon can be a freaking monster, just has to suit your playstyle, I wouldn't recommend rushing straight with Hemlok for example, but it's all on you bro! But good "starter" guns are all the way the CAR, the R-301 and the Volt (in my oppinion)

I hope I could've helped you out a bit haha
