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.

Upon receiving it put it on a lower and took it out into the wastelands. I conducted a 50 round test firing with no problems. The fit and finish are perfect and I’m very happy with the upper. It is a perfect representation of a Colt 635 SMG upper. It ran perfectly with standard milspec fire control group, Anderson lower and Brownells Colt type straight 32rd mags.
Couldnt be happier. Mixed with a cmmg lower and a 9mm buffer it just runs. Very consistent ejection.
