A paintball gun
You can purchase a Spyder Paintball gun directly from the Spyder Paintball website. There are also options for new or used Paintball guns on eBay. There is a wide variety to choose from.
.68 caliber. the paintball standard.
no pirahnas are lower quality knock offs than spyder, they are not too bad for starters but spyder is better if you have a choice
The salvo has more accessories and has a better feed neck and stock then the Mr1.
as long as it is spyder threaded yes
Standard .68
Tippmann 98, very durable and easy to fix.
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 MR100 Pro is the RIS Quad rail system that fits the Spyder MR1 paintball gun.
no. only if the title of your paintball marker says "electra"
