Thought a review of the Scorpion VZ61 SMG might be of interest. This particular blaster is very available, several gel blaster outlets list it in their stock, price averages around $199, this unit set me back $159 with a seller discount code.
Manufactured by Gel Fire, same people who make the Cyberpunk Quasar DR-12. This review won’t go into the unusual offset gearbox in this blaster :
That’s been covered in this forum already, forum searching “Quasar” will take you to a pretty solid look at the gearbox by Bigmuthadrums and Chapinb.
What You Get :
VZ61 SMG blaster
Stick Mag
Drum Mag
7.4v battery & USB Charger
Eye Pro (garbage)
The blaster comes fully assembled minus the battery cover (in an accessory bag with the rubbish charger, battery and a screwdriver you couldn’t tighten your Raybans with).
First Impressions :
Very solid nylon build (think Kriss Vector), decent Allen head assembly screws, steel folding stock/brace, alloy inner barrel (7.4mm measured, but more likely 7.5mm standard approx 12cm long), falls short of the outer barrel by about 10mm so no extra barrel length to fit a hop up.
Interesting also that the feed tube on the mag is positioned at the rear… obviously to get as much inner barrel length as possible. It would be viable to lose a few centimetres off the alloy barrel so that with a short hop up on the overall length would be roughly the same. Nylon outer barrel would need to be trimmed back to suit.
Both stick and drum mag have a solid feel, quality nylon. 55-60 gel capacity for the stick, 220-230 for the drum. Has a functioning ambi charging handle, fire select lever and trigger are nylon build.
The stick mag fills through a flip down hatch on the front of the mag, the drum through a hatch accessed by rotating the lever on the front face of the drum.
Interesting to note the stick mag was a very neat fit in the magwell with minimal movement, while the drum was tight to the point of unuseable. It required a fair bit of sanding down on the sides of the mag neck to get an acceptable fit and to allow the mag catch to function properly.
Both mags are lacking gel stoppers as is the t piece so mag out means gels everywhere unless you keep it upright. May look into retrofitting stoppers, but as this is mostly ornamental, probably not.
Trigger pull is light, actuating a Gen 8 style micro switch, there’s a little bit of dead trigger on the pull but could be easily taken up with a pad on the trigger if it’s an issue for you. The trigger safety is mechanical and feels fairly flimsy, like it would break the lock mech if a heavy hand tried firing from safety.
Fire select lever is reasonably positive, there are three settings, safe, semi auto and full auto. Weirdly, the sequence is safe to full auto to semi, similar to an AK.
Fire control is via a MOSFET located in the handgrip, four screws out and it’s accessible, although replacement MOSFETs may be hard to source.
Steel folding stock is functional but puts the blaster in an awkward position. It is easily removed (one screw and nut) if you’d prefer to run it as a straight up pistol.
Battery cover is awkward… it’s designed to fit only one way, a spring loaded detent lug (circled) on one end locks it into the grip. The lug is depressed by rotating the lanyard fixture on the base, and a firm upward pull frees the cover. The problem is the rotating fixture is at the opposite end to the lug, makes it difficult to lift the flush fitting cover upwards, and there’s no room for a fingernail. It can be removed, but it’s awkward.
The Wiring :
Well… mine arrived with a chunk of insulation out of one of the battery lead wires, required pulling off the JST connector and heat shrinking to cover the bare wire.
The wiring from the MOSFET was a tangled mess just left loose in the battery compartment. Not correctly routed and didn’t allow room for the battery. One red wire had been pinched quite badly on a screw post and on the outside of the grip on assembly.
Replaced the pinched wire, rerouted the whole loom (there’s a fairly large space in the body of the shell to accomodate it) and freed up some space in the grip for the supplied 7.4v battery, which does NOT fit regardless due to being too long.
Tried an old 11.1v Vector checker battery and it fits well with room for the balance plug and JST. It still requires some careful placement but it fits. How long the MOSFET survives running 11.1v is unknown, but one of the tiny 7.4v lipos would be fine.
Performance :
Not too shabby for such a small unit. Seems a little picky on gels, it didn’t like the smaller ones. LDT Heavy Milkies showed 180FPS on the chrono, WI Reds clocked 160FPS, Pinks averaged 170FPS, 165FPS for X-Force Ice Balls and very suprisigly, 190+FPS for Ultra Elites… yes, it will spit Ultras out quite efficiently.
Rate of fire was a bit all over the place, but that would be due to gel issues. Chrono showed around 17-18RPS, pretty much like a Vector on 11.1v lipo.
Conclusion :
Mine’s a display piece, so a lot of issues like performance, reliability, etc don’t really matter.
Would I buy it for kids? No… there are better options. The grip is large and a little uncomfortable for small hands, the trigger although light feels weak and would probably end up broken, the battery’s small and a little awkward to replace and every mag change will see you knee deep in gels with the lack of gel stoppers in the mags and t piece.
It’s a fun unit, hits harder than a Beretta M92 on 14.8v and has better trigger response, so as AEG pistols go, it’s not half bad. Fun for the backyard and hardhitting enough to get your kids yelping. But as a skirmish blaster it’s got a lot of shortcomings.
Overall, QC issues with mine aside, it’s going to be interesting to see what comes next from Gel Fire. Their build quality is reasonably good. 
Did I mention their instruction sheet is written COMPLETELY in English?
POST EDIT :
Couldn’t resist the temptation to fit a hop up to the VZ61.
Cut down DK-13 hop up, required losing the whole nylon outer barrel up to the rings, reduced the inner barrel by 17mm to snug the hop up against what was left of the outer. I managed to retained the original overall length and no loss of FPS, much improved accuracy.
There was a tendency to fire two gels now and then. Checking the bottom of the t piece I could see it was a little spacious and was allowing the gels to sit side by side.
Inserted an alloy bush 9.0mm OD X 8.0mm ID into the t piece to keep the gels in line, so far no more double feeding.
Thought about reshaping it, but it’s all about the look for me, so no. They do look cool with the brace folded, just need a long black leather coat and a pair of sensible shoes made in The People’s Shoe Factory and the KGB look’s complete.
