[DnD 3.5] Character built around futuristic weapons

[theonesin]

So, I've got a desire to make a character involving the futuristic weapons from the Dungeon Master's Guide. Specifically, the antimatter rifle.

I'm not really used to building ranged characters though, especially ones with unusual weapons like this. Are there any guides or other suggestions that I could use to get a start on where to go with this?

Ultimate Archer Handbook (http://community.wizards.com/go/thread/view/75882/19866186/The_Ultimate_Archer_Handbook) has a lot of good information on ranged combat. Much of which should apply to the use of a firearm.

You could probably utilize resources like Item Familliar, to self enchant your rifle. Ancestral Weapon would also work.
