Forged Flattop Upper Receiver - Forged Front Sight Base Match Grade Chrome-Moly 1:8 Twist 300 BLK Heavy Barrel. They are headspaced and test fired.
To use a Mid-length or Rifle-length Handguard you must get the Low Profile Gas Block.
These come complete with the Charging Handle and Bolt Carrier assembly.
6 Position Mil-Spec Car Stock and Complete Lower Parts Kits with Grip to finish off your build. 
We highly recommend using Magpul 300 BO Mags to reliably hold the bolt back on the last round.
