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

This is a quality upper receiver!!! It was exactly what I was looking for. Fit and finish are excellent. No issues with the operation, and it holds tight groups. I had prepared myself for an extended delivery time based on other reviews, but I was pleasantly surprised when I received it in just a few short weeks. I highly recommend TNTE Sales, and I will definitely order from them again.
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
