Definitive Arms AK 103U Rifle , Chambered in 762 x 39  semi auto .These Custom Rifles are being built exclusively for Atlantic Firearms and Copper Custom Armament  . Definitive Arms attention to detail is incredible with features normally only found on rifles built by Krebs Custom or Rifle Dynamics . With a long list of enhancements added to this firearm the 103U is destined to be one of your favorite shooters. The rifle has been shortened by cutting down the barrel and moving the front sight back .Shorter than full length sights, longer than Gas block sights. We believe this to be the happy medium allowing the shooters to utilize the sights at longer distances while maintaining a clean sight picture during up close firing . The sights & gas block are aligned with the bore of the rifle to improve accuracy and eliminate the dreaded canted sight problems. The barrel is target crowned , operating surfaces polished  and the gun is tuned to run as smooth as silk .This is only a brief description of the Custom upgrades preformed on this rifle please review the Spec Sheet below for more
