the plastic piece directly under your feedneck? That's your ball detent, it prevents balls from double feeing. good luck finding that part sold seprately. I helped my neighbor kid find one a few years ago and it too about an hour of searching the internet.
no duct tape won't work.
what you could do instead, is drill it out for an autococker detent ont eh other side and fill in the hole. It'd be a lot of work, but thaen agian, who knows if you can even buy that peice by itself.
Anotehr idea is to finda way to affix an o-ring in halfway through the hole so it acts like a detent.
Hmm... price? and I've heard lots of things for good starter guns. I've heard Tippmann 98, I've heard Tippmann, X-7, I've heard Orion, I've heard a lot of Spyders... So hard to choose... From what I could guage from using one last time I went paintballing, the Icon I used was pretty good, except the trigger was way too sensitive. Anyways, what's the price of that Spyder you're talking about?
Thanks dude. That really helped, I just got back from the store and I got a Spyder Sonix. It's pretty sick. Even with the stock barrel it's almost dead-on for accuracy, and I got it for just under $100.
