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 Extended A2 flash hider is pinned and welded for NFA complaince. We recommend a 55gr or 62gr bullet for best accuracy. The front sight is a A2 with bayonet lug.
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.

Shot several hundred rounds through it without issues, plus the aesthetic and feel made the wait well worth it.
Waited a while for this. And I have to say it was more than worth the wait. I've only done 200 rds through the upper but it handles shitty steel ammo like a champ. Gassed very nicely. Overall a very great upper. Would recommend to anyone who wants that retro look
