i currently use the viewloader revalation and have no upgrades
I think you shoud get a doulble trigger. My opinion is with a double trigger you can shoot faster.
everything besides it has a single trigger.this is a good bigennirs gun [cheap to.] it was my first semi outo.And i've had no problems.[yet] I have lost with it but the other guy had a pirrana VTL upgraded also.
it has no double trigger. [it is also bad for the other team.] otherwise it's exellent.
If your a beginner buy it . If your not a bigenner buy it. Just buy it
