Weapon Combinations

Take a look at this kick ass M4A1 mod:



It's a Remington 870MCS pump action shotgun mounted underneath an M4A1! This sounds to be quite interesting.

The Armalite AR10:



Note under the barrel it has a bayonet lug.

The AICW (Advanced Infantry Combat Weapon) which is a combination of an F88 Austeyr (similar to Steyr AUG) and a 40mm grenade launcher:



I am fully aware too that Z8 refuses to make grenade launchers, but I believe it will not be overpowered IF the grenades are weaker than normal hand grenades and have a smaller blast radius. The only difference to a normal grenade is that it explodes on impact and travels a straight path instead of a arced path, which means it can't be bounced off of walls or thrown over obstructions.
