Spyder Victor II
WGP BOSS Dark Raider
Apple Green Spyder Xtra
16" Thunderpig barrel
ACS Delrin Bolt - which I dont use
Honestly, if your not willing to or do not have the money for e-upgrades and you only play woodsball or scenario, the stock gun worked great for me.
Gun looks cool
stock barrel is awesome
easy to strip
no-tool adjustable velocity
Too tall with stock feedneck
Beavertail is crap
Eventually replace parts and make repairs
I have had my Spyder Xtra for probably 8-10 years now. It has worked good for woodsball over the years. Overall I have not had too many problems with this gun and when it is working, it is awesome and I love it. I also own a Spyder Victor II and a BOSS Dark Raider, and I have used tippman 98's and Alpha Blacks, and would use the Xtra over the others any day.
I have a 16 in barrel for it but actually use the stock one instead because in my opinion it works better (the barrel must just suck). I purchased an ACS anti-chop bolt for it and had bad luck with it (would pinch the paintball in the marker and get stuck???). But I don't really care because I use the stock bolt and it works great and doesn't chop ball (have only ever chopped less than 10 balls in roughly 10 years).
Over the years I have had to replace many o-rings and tighten many screws. Recently had recocking problems (very frustrating) but found that the problem was the cup seal. The pin would not thread into the stripped cup seal, so I super-glued the pin into the cup seal and the gun worked awesome since.
Obviously now they have changed the xtra quite a bit since my ancient apple green Xtra 10 years ago, but I would recommend this gun to anyone who just plays woodsball and is looking to play recreational paintball and not take it too seriously.
JUST REMEMBER TO KEEP IT OILED ESPECIALLY THE BOLT!
