Some questions

[storm33229]

I am pretty new to this area. I have built a PVC Pneumatic marble gun in the past(quite recently).

I want to get a trigger... what should I use?
What does 'Stock' mean?
Why would I use a modified sprinkler valve?
Is there a post/site that provides basic parts required?

Thanks

Spud Wiki at the top of the page is where you can research for all the information your looking for. When you figure out exactly what you want to build next, local hardware stores carry all the parts. When i first found this website, i read in the wiki for 3 hours straight the 1st time there, it's the best place to start.

<a href="http://www.bcvids.com/store/product_inf ... 2">Mdified Sprinkler Valves</a> open by squeezing the blowgun lever, and offer better performance that electronically opened valves.

For a trigger, you could use a blowgun.
A stock is the part of a rifle that goes against your shoulder for easier aiming.
And a modified sprinkler valve can open extremely fast, therefore shooting harder and farther.
For a site/post, just search. It really isn't that hard. Like jrrdw, I spent about 2 hours on the spud wiki my first time seeing it.
