All modifications are unlocked. Including ammunition. I play with it the same way I play with the t47 (4.0), where I play well. I use Br271 for everything.
I didn’t understand what you meant by fire adjustment, and vertical / horizontal adjustment.
This is the most ridiculous statement ever made. At 4.7, it clubs everything it faces, even when uptiered. IF ANYTHING, it’s BR should be increased to 5.0.
