With ammo, optics, bipods, and support gear. You're talking 20-25 pounds of guns alone. Plus body armor, comms, life support gear, pistol and mags, navigation equipment, 2 primary lights and 1 specialty light, food, shelter equipment.
Honestly for a guerilla set up the best bet would be a Colt LE901 with a 20" barrel 15" handguard, QD suppressor and a 14.5" M4 style upper.
