    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. 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.

      Colt 727 Style XM4 A2 Upper 14.5" Ext A2

      Posted by Dave S. on 31st Mar 2022

      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.

      Great for XM4/BHD build

      Posted by Ryan on 29th Dec 2020

      Shot several hundred rounds through it without issues, plus the aesthetic and feel made the wait well worth it.

      Great Upper

      Posted by Ethan on 17th Nov 2020

      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
