I recently purchased one of those v4a1's as a back up and I was surprised at performance. Main went down so I've been using this all season. I am quite trigger happy so I have probably put 12000+ rounds through it and not one hiccup. After playing 6 or so games I am finding it easy to compete if not out range most other guns. Shoots straight and last chrono with .25's was 350. Kind of sounds and feels cheap when shooting but shoots well. With that said, definitely a good starter gun, but once you hold some metal you will wish you put the 260 bones towards something a bit nicer.
Oh and mine was branded as Techfast? haven't found much on them but looks like a JG.
