I did some testing. First, it does have collision properties with terrain like hedges and lower elevations as well as vehicles, though it seems to just phase through others such as haystacks.

PTRS does the same but has not projectile.
Second, the Weapon DOES have AOE, AND it has attack ground, which leaves me to believe it is in fact a projectile.
It has AOE but very small of 0.5.
It uses accuracy 0.675/0.618/0.56 while Ostwind uses AOE (0.05/0.0375/0.025)
The strafe on the other hand uses AOE and not accuracy so it can use both types of attack.
(maybe I can test later to see if it has a projectile)
Ok as far as I can tell it does have projectiles but as I pointed in my original post comparing an accuracy bases weapon with an AOE based weapon is rather misleading. Each has it pros and cons.
