Two factors:

1. There is more money involved (both professional and donated) in securing gun rights.

2. Gun rights have a stronger legal basis than privacy rights, which only exist at a federal level due to fairly recent Supreme Court rulings (last 100 years).

Also, the NRA actually isn't a great gun rights org. They're more of a hunter's rights org. For example, they supported the current excise tax on guns that funds public land management (good for hunters). The Second Amendment Foundation is a much better organization for general firearm and self-defense rights.

For other rights, we have great orgs like the EFF and ACLU. They're just working with a weaker legal basis.
