Product Description
This upper offers a 1:7 RH military twist rate. It is made of 4150 chrome-moly steel with chrome lining and HP tested. The upper is Mil-spec and at a length of 14.5" it's pretty darn short. A A2 flash hider is the default flash hider. We recommend a 55gr or 62gr bullet for best accuracy. The front sight is a A2 with bayonet lug.
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.Product Videos

I saw these just as I was getting out of the Marine Corps. TNTE built it right and rounds out my collection just perfectly. This upper is a good match with an Anderson or Aero Precision lower! It’s a good off the rack shooter.
