Fallout 3
The only upgrades seen in Fallout 3 are scopes, the occasional use of silencers, and the use of expanded magazines. Other differences between unique weapons do not technically count as weapon mods, seeing as there is only one of each unique weapon. There is no way to get any weapon upgraded.

Fallout: New Vegas
Any of New Vegas's weapons can be modified with several mods. Only a merchant can fix one up for you, though.

There are multiple weapon mods for every weapon, and a maximum of three weapon mods can be attached to any one weapon. Once any weapon mod is attached it is permanent, so be wise in what you want to attach. For example, while an extended magazine is almost always beneficial, a scope has pros and cons. It may increase maximum range, but it may also worsen the minimum range, making it harder for close combat.

List of available weapon mods

 * Scope - Increases maximum weapon range and precision.
 * Extended Magazine - Increases the maximum number of rounds or cartridges available in a weapon.
 * Custom Bolt - Smooths the sliding of a bolt in a bolt operated weapon, thus speeding up the rate of fire.
 * Brass Plating
 * Maplewood Grip & Stock
 * Extended Feeder Tube - Increases the maximum number of rounds available in a weapon.
 * (Speculative Name) - Increases spooling time on the minigun.
 * (Speculative Name) - Decreases the spread of bullets from the minigun.
 * Adjustable Laser Focus - Adds a precision sight to the laser rifle.
 * Magnetic Accelerator - Reduces AP cost to the plasma caster.
