5.56 20" A1 Rifle length Upper 1/7
Here is one of our favorite custom builds. We decided to try and rebuild the old school M-16A1. These are using .625 Government barrel with a 1/7 twist. The pencil barrel is made of 416SS steel with a 5R polygonal bore, and the barrel has a melonite QPQ finish inside and out. Upper receiver is black Type 3 hardcoat anodized. Handguards are our new reproduction.
