Galil is like a faster version of the AK. Weaker Power, probably close to the SCAR-L, more lighter weight for better maneuvering tactics and abilities. It's not in league with the AK or anything else. It's just a good comparison.
The new shotgun is probably like a pump action shotgun, however, it shoots bullets at a time. Like... Shoot-->Animation -->Shoot.... --- Kind of like that other shotgun in the Counter Strike Series. It has better consistency, though the spray pattern is no where like the dual desperado... Dual desperado is decent at medium range, but I don't think this gun would have the potential near that...
I don't think the rifle will be for ZP, but for GP. It sounds like a fit and well thought choice if you think like me. Shotgun for ZP because in terms of power and liability it will overcome the XM in many ways.
