Product Description

Here is one of our favorite custom builds. We decided to try and rebuild the old school C7 M-16A1 Carbine These are using a true M-4 carbine barrel with a 1/7 twist. The barrel is made of 41V50 steel and the chamber/bore is chrome lined. We have also used a A1 Bird cage flash hider on it. C7 Upper receiver is black finished. Handguards are surplus USGI Mil-Spec.


Take a look at this great article about our upper http://www.gunsandgunsmiths.com/retro-ar-project/


This item carries a lead time. Typically it is 8-12 weeks. Due to product availability lead times may vary.


Warranty Information

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.

  1. Best Colt 723 upper EVER! 5 Star Review

    Posted by on 19th Dec 2017

    I was able to get one of these pre release, and man am I ever happy about it! It looks amazing! It's a dead ringer for the "CAR-15s" of the late 80s and early 90s. It also shoots incredibly well! Mine shoots about a half MOA at 100 yards. I don't think you can go wrong with anything you find on the site here.
