Having tested every FRT on the market from $60 Amazon specials to $500 boutique units, here’s what matters:

| Finish | QPQ nitride | Phosphate | DLC coating |
| Lifespan | 10k+ rounds | ~2k rounds | 15k+ rounds |

Why This Trigger Wins
After running 750 rounds through this unit on our Spring, TX test range, three advantages became clear:
