spyder xtra, whisper barrel, ricochet ak, esp electric trigger frame, 20 oz tank.
good varity of spings.
These springs are actually made for spder too. I got these so now i don't have to get my spring cut anymore. Theres nothing much to say about spings other than i paid $14.99 for them at my local paintball store.Most of the time i use the the lowest spring on my spyder rigt now.
Get these springs if you don't want to get your sping cut anymore, they are the best out there right now.
