The AR15 pistol upper pictured is assembled by competent armorers in the USA. The barrel is chambered in the popular 5.56 NATO cartridge, has a 1:7 twist rate (perfect for stabilizing the bullet in that short of a distance), is made from 4150 chrome moly vanadium, it also has m4 feed ramps, and is nitrided for maximum wear resistance.
The Keymod handguard can accept keymod accessroies and provides a minimalist approach to the AR platform. You can add picatinny rails to the handguard at your leisure and the anodizing is sure to hold up to the harshest conditions.
Charging handle and bolt made from 158 Carpenter Steel are optional and can be added to this purchase for a combination that is ready to throw on any lower.
