The UPC 556 is a highly stripped UMP 45 chambeered in the 5.56 NATO cartridge. It is very lightweight coming in at 6 lbs. due to the extensive use of polymers and alluminum parts. It's accesories include the Trijicon MRO and foregrip. It's rate of fire on fully-automatic is around 650 RPM and it's effective range is around 700 yards with a 15" barrel. It is very effective in cqc because of it being a lightweight, low recoil rifle but it isn't very compact because of it's length. It has a unit price of 1,400 USD (not including optics) and a shorter model with an 11" barrel can be purchased.

Thanks YuukaNeko for this awesome rifle! Thank you everyone for your support! Enjoy!
