IDK if anybody else has noticed, but the hunting rifle's ironsights are off by like 1/4 of an inch to the right. You can see it more precisely by zoom aiming in 3rd person mode and while still holding the aim button, go back to first person, this should keep the crosshair visible while in ironsights mode.

I noticed the sights on the M1 Garand are a bit off, too. I went to all the trouble to get that thing and have to shoot from the hip most of the time because it's shooting to the left quite a ways.

I noticed this with other weapons as well like the hunting shotgun (not really an issue since it's not exactly a surgical strike weapon).

RH_Iron sights is making various fixes to certain iron sights, but is yet to remedy the hunting rifle yet. I expect it will get the treatment soon, as long as they can get this new version to work. I definitely agree that there are too many misaligned sights that made it into the finished game. I was mad when this machine couldn't hit a damn thing. -____-
