Product Description
5.56 20" A1 H-Bar Rifle length Upper 1/7
Here is one of our favorite custom builds. We decided to try and rebuild the old school M-16A1 HB (606,611,615,621). These are using .750 Government barrel with a 1/7 twist. The HBAR barrel is made of 41V50 steel, and the barrel is chrome lined. We have also used an A2 Bird cage flash hider on it. Upper receiver is black finished. Handguards are our new reproduction.

Custom 603 Upper
Even a pandemic won't stop TNTESALES from delivering an absolutely amazing upper! I placed this order in the spring, just before the madness began. Even as supply lines dried up, my emails were and questions were always answered. When I informed them that my build was a Christmas present for my VV Dad, they offered an alternative upper that helped me finish the project. My Dad was ecstatic and absolutely loved it!!! I will be ordering from them in the future and highly recommend their products!
