Looking for a line-of-fire / line-of-sight mod

[BRBonobo]

Does anyone know of a mod which brings the line-of-fire more in line with the line-of-sight? I would really like my guys to be able to raise their guns to eye level and shoot at whatever they can see.
On a related note, any mods that mess with how accuracy is calculated to make cover more useable would be appreciated.
Thanks in advance!
