    Product Description

    This M4A1 Barreled Upper Assembly is complete and ready for you to add your choice of Optics or Rear Sights. The highly accurate 11.5” M4 Heavy profile barrel is chrome lined and machined from 4150 Chrome Moly Vanadium steel - rifled 1 x 7 Right Hand twist. The barrel has flats to accommodate the M203 launcher system. An A2 Flash Suppressor and standard A2 F-Marked Front Sight are fitted. The machined aluminum flat top Upper Receiver is complete with Bolt Carrier Assembly (if selected), Charging Handle (if selected), Forward Assist, and Ejection Port Cover.

     

     

     

    The Knights Armament Rail Interface System (RIS) was designed at the request of the United States Special Operations Command (SOCOM) for the SOPMOD program. It allows the individual operator to free-float the M203 grenade launcher without additional parts.

     

    Other Details

    All TNTE uppers are custom built using exacting tolerances by highly trained armorers. Your receiver and barrel are torqued to a spec of 55-65 +/- for best accuracy. Then your feed ramps and chamber are polished and de-burred. All uppers are checked for proper head-spacing and test fired to ensure reliability. Beware of sellers who refuse to tell you where their parts come from because all uppers are not created equal. We use only Milspec or higher quality parts for your upper. TNTE uppers are built with professionals in mind, we go through them with a fine tooth comb to make sure when you need it most it will be there for you. Our custom stripped uppers are covered by a one year warranty. Complete uppers have a limited lifetime warranty.
