Other DetailsAll 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.
