The Northernland Prototype Drop Rate Is Nonexistent

I have no idea why this drop rate is so low. I literally just want a catalyst and claymore prototype but the northernland prototypes don't even drop in the first place. The drop rate is so low. The only thing I can say is that there is a drop rate as on one occurrence, I got one. This drops rate needs to be increased.
I hope you enjoy(ed)!
