The IW-80 A2 is a 5.56x45 caliber bullpup assault rifle that appears in SOCOM 3: U.S. Navy SEALs and SOCOM 4: U.S. Navy SEALs. It is based on a real life British Assault Rifle called the L85. 

SOCOM 3: U.S. Navy SealsEdit

It has a controllable amount of recoil. It shares ammunition with the M4A1M16, G36C and 552.

There are some problems with it however, like that ammo can be scarce and that you need to finish the game on Admiral difficulty to unlock it (alongside the STG 77).

SOCOM 4: U.S. Navy SealsEdit

It appears again in SOCOM 4: U.S. Navy SEALs.
