Angle of depression is locked too high. You can't use a bipod and aim lower say about 100 degrees. This means you can't shoot at anything below a reasonable field of view like down a stair way or below a window/ledge making your engagments strictly to things that are perpendicular to your view.
Already pointed that out in another thread along with others. We have also mentioned undeniable placement anomalies , like you can place the spikes on a 1 cm wide iron rack but you're unable to place it on sandbags or flat concrete surfaces, begging to be used. Woefully missing that familiar "thx for your findings, I've passed it to the team" acknowledgement. Disheartening to say the least. "Hello?! Where is everyone? Say something!"
