Does anyone know the points requirements for each lvl on a weapon

[Edward Edgemenace]

50, 150, 300, 500, 700,
900, 1100, 1300, 1500, 1700,
1900, 2100, 2300, 2500, 2700,
2900, 3200, 3500, 3800, 4100,
4400, 4700, 5000, 5300

Ah, thanks Edward, good start! Where did you find it, I really turned the sock drawer upsidedown

I got myself mixed up. When your weapon is level 24, you can level up (5,300 points) but once it is mastered, it is mastered. So, there ya go. Found the last three, unambiguously.
