PEO Soldier's Small Arms Dump.

PEO Soldier has been kind enough to provide a photographic over view of Army weapons.  These are the most interesting.

The M26 Modular Accessory Shotgun System (MASS) provides Soldiers with
a 12-gauge shotgun accessory attachment with lethal, less-than-lethal and
door-breaching capabilities.

The M192 provides a lighter weight, low-profile mounting platform for the M249 and M240 for controlled, sustained, and accurate fire at extended ranges.

The M320 Grenade Launcher enables Soldiers to accurately engage the enemy in daylight or total darkness with a safer more reliable grenade launcher. Much more over at their site. Check them out.
