Weapon perks
Equipped weapon gains experience as you kill NPCs or use Upgrade Parts on it. Upon gaining enough experience it will unlock new perks and their color will change.
First three perks on tier 3 gear are always predefined. Some tier 4 items have random perks even on first three levels.
Fourth perk you are able to chose by dialog window once you unlock it. Exception to this is when you level your weapon by Upgrade Parts then perk will be random.
Fifth perk is always random.
Sixth perk (so called "legendary") is picked from different table of perks instead of regular one. Legednary perks works only against NPCs.
Every weapon can be upgraded by Roger or Cotsford (Vegas) to gain one additional perk.

Rerolling
All perks on weapons can be rerolled by Boyce in Junktown or Vault 8 (yes there are two of him). The cost is in local currency and requires the same amount of currency as the experience required to get that level. The perk added by wattz cores or t4 parts can also be rerolled, which is listed as number 7 in the following table. Rerolling is random, so expect to potentially spend a lot of currency before getting exactly what you want.
| Level | Cost |
|---|---|
| 1 | 10,000 |
| 2 | 75,000 |
| 3 | 150,000 |
| 4 | 1,000,000 |
| 5 | 5,000,000 |
| 6 | 50,000,000 |
| 7 | 50,000 |
