LMG Bipod Glitch

I found a bug with the LMG bipod system while I was playing on Operation Metro conquest large where after a few seconds of firing, and smoetimes randomly, the effect of the bipod on the recoil was nullified. What I mean is that thye indicators showed that the non-ADS accuracy was normal for a bipod LMG, the recoil would suddenly jump to as if I had no bipod equiped. This happened on both of the LMGs I tried that match: the M240B and the PKP Pecheneg. So, with that out of the way, where do I report this bug so that it will be fixed, since I can't report it because I don't know where to submit it, if any devs are even reading this, or even care. but with any luck, this bug will be fixed.
