AR15 Upper Reciever Build

Detailed video on how I built my AR15 upper receiver. Building a AR15 is super easy. You only need a few tools and you’re all set. Anyone and I mean anyone can build one. Don’t let anyone tell you you need some shop to assemble it for you…you can do it! I mentioned in the video to use a 3/16″ drill bit…use a 1/8″ drill bit to check barrel nut and gas tube inlet alignment.

  1. You don't need Loctite on the endcap, the holes are for flat head screws in the sides of the forearm. You should also use anti-seize on the barrel nut and compensator threads. Other than that criticizm, good video!

  2. US ARMY M-16   TECH MANUEL        TM-1005-249-23&P         page   3-31       Google and read     It is clear how a barrel is 3 times tighten and  TORQUE to 30 foot lbs        Feel good tightening doesn't work in the real world .   PROPER SPEC s do.      JOHN

  3. BAD INSTRUCTIONS.     THIS IS NOT HOW YOU INSTALL A BARREL ON A AR- 15 UPPER.  A TORQUE WRENCH IS A      MUST     FOR ALUMINIUM ALLOY RECEIVER.  Grease is also missing.         JOHN A BUDESA    SGT USMC  ( small arms gunsmith, and expert—  AK s     AR s
