Here is the list of all the weapon glitches, bugs, and discrepancies:
Credit for the list goes to Blame Truth

-The M9 with TacKnife's iron sights are off, they shoot below the tip.
The M9's sights are aligned with any other attachment.

-The M9 with Silencer will still show you as a red dot on the mini map when fired.

-The MG4 with Silencer will still show you as a red dot on the mini map when fired.

-The M240 with Silencer will still show you as a red dot on the mini map when fired.

-The MG4's iron sights are off, they shoot WAY below where the tip is.

-FMJ on the Spas-12 doesn't work.

-The FAL with Red Dot Sight is very off, the bullet lands to the bottom right of the dot.

-The Desert Eagle's sights are off.

-The M93 Raffica's ironsights are off and shoot to the right of the tip.
They are also slightly off with the Red Dot and Holographic sight too.

Discrepancies:

Some weapons have differences in themselves with some attachments, or are different from all other weapons. These differences are most likely intentional for balancing purposes.

-The FAL with a Holographic sight gets its damage boosted from 55-35 to 55-40. Stopping Power ONLY has an effect on the FAL with the Holographic sight, making it a consistent two shot kill at any range. The FAL without the Holo sight gets virtually no benefit from Stopping Power.

-The M16 with a Holographic sight gets significantly less recoil/spread than without it. With the Holo sight, it gets less recoil/spread than the FAMAS.

-The AK-47 with ANY attachment except ACOG will add idle sway when aiming down the sight. Thus, it is best to use it with no attachment at all.

-The AA-12 with Extended Mags gets 2 times its original magazine size (8 to 16) as opposed to other weapons only getting 1.5 times their orignal magazine size.

-The M93 Raffica and G18 machine pistols, when Akimbo'd, get a smaller and more accurate hip fire reticle. Other weapons with Akimbo get a larger reticle.

-The Model 1887 shotgun with Akimbo has less effective range than a single 1887. This is due to an old patch IW made to nerf the Akimbo 1887's for balance purposes.
