While both of them are truly poor quality guns, The better one in this case would be the mongoose just because it has eyes, which will cut down on the amount of paint you will chop. I would recommend however that you look at the Azodin Kaos which is of much better general quality than sypder or diablo guns.
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.
The sonix, because it has an actual hand grip.
no. only if the title of your paintball marker says "electra"
It is not recommended you do this for safety reasons.
Spyder Sonix can use any Co2 or HPA tank
Absolutely!
Buy a Spyder E-trigger.
Most likely the striker o-ring is broken or needs to be lubricated. It could also be that the sear is work, or the mainspring could be worn. Take it to a local paintball store to have it looked at.
The comparison between Tippmann 98 and Spyder Sonix largely depends on personal preference and intended use. The Tippmann 98 is known for its durability, reliability, and ease of maintenance, making it a popular choice for beginners and scenario players. On the other hand, the Spyder Sonix is lighter and offers a more compact design, appealing to players who prioritize mobility. Ultimately, the "better" choice will depend on the specific needs and playing style of the individual.
On the bolt cap there is a small twistable screw. Put an Allen wrench in there and it will go up or down. NOt sure witch way does what though.
Disconnect the air source, pull up on the bolt, and slide it out of the back.
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.
