Nope, its the same VSR-10 hop up cut. With the PDI hop up, you do need a AEG barrel, which is seen by a plus for some, but with the 430mm Laylax barrel for VSR-10 cut, what more do you need?

Oh yeah, I guess the laylax one too... but I've heard bad things about that hop-up. I'd either go with PDI or TM precision (if you can't get your stock one working right).
