They are the same gun with slight variations. The sonix has a hand grip, clamping feedneck and different ASA hose and the victor is slightly cheaper because it doesn't have those things.
Neither of these guns are very reliable or what could be considered "good"
I would look into the Azodin Kaos before buying either one of these.
The sonix, because it has an actual hand grip.
It depends on what you are going to use it for... If you are going to play more speedball, get the sonix... If you are going to play more woodsball, get the MR1.
Spyder Sonix can use any Co2 or HPA tank
Absolutely!
No, The Electra is Spyders "step up" from the victor. It is inside the same as the victor, but also has electronics and other features. The same with Tippmann, Azodin, and many other companies, they release a low, mid and "high" end gun together. The victor in this case is their cheapest and most "bare boned", then the Sonix, and then the Electra.
Buy a Spyder E-trigger.
It is not recommended you do this for safety reasons.
they are the same design so i would say whichever is cheaper
The spyder victor is a more reliable gun than the JT. You should also look into the Azodin Kaos.
Disconnect the air source, pull up on the bolt, and slide it out of the back.
I have a spider sonix,and I can shoot probably about 1000 before it gets low
It is a low quality, cheap starter marker. It shoots, and that's about it.
