I noticed that the grendel has inconsistent rate of fire. Sometimes it's fast, as if you have double Fire rate enhance, and sometimes it's normal.

Someone care to explain?

It has 2 fire modes: Burts (fires 3 bullets at once) and Semi (fires 1 bullet at a time)!

Using auto, the rate of fire is sometimes fast, like fast, and sometimes it's slow OR doesn't fire at all.

In fact, I am noticing various anomalies with the Feline as well. Like in intense combat where I reload and hold my finger on the trigger while trying to turn on ADS, it won't and the feline will shoot, but there is no sound at all.
