Shots from the ASP-1 Kir seem to be more noticeable to enemy AI than those from the MAR-10 equipped with a suppressor. This is an issue because the Kir has an integral suppressor, and fires a subsonic round, while the MAR-10 fires a supersonic .338 Lapua Magnum round, so shots from the Kir should be at least as well suppressed as those from the MAR-10.
I'd request that the bullet and rifle settings which affect detectibility for the two weapon systems be re-examined, and adjusted if necessary.
