Save big dollars while shooting for pennies!!!

The Huldra Mark IV 5.45x39 Carbine Complete Upper comes complete and ready to go into any mil-spec AR 15 lower. Huldra's Adams Arms patented piston system technology will run cleaner, cooler, and longer than any other AR. The piston system parts and the barrel have been treated with our salt nitride meloniting process making them harder than hard chrome.

The 5.45x39 caliber bullet matches high muzzle velocity with excellent sectional density, resulting in a flat trajectory and good penetration. The standard ball cartridge will penetrate 5mm of steel plate at a distance of 350 meters. The lowered recoil impulse of the 5.45mm cartridge (verses the 7.62x39mm) has a beneficial effect on accuracy. The 5.45x39mm cartridge is an excellent round that offers comparable penetration, accuracy and lethality to anything fielded by NATO. More importantly, 5.45x39 ammunition is less expensive to shoot! This upper has been designed to handle dirty and corrosive surplus ammunition. The bolt and bolt carrier have been protected by an ion-bond finish. These processes make the parts more corrosive resistant and harder than hard chrome. Now you have the ability to shoot the inexpensive corrosive mil-surplus ammo without the fear of the parts being unduly worn. Each upper also comes with a 30 round magazine and a Wolff Extra Power Hammer Spring to ignite the older hardened primers.

Our melonited corrosive resistant CrMoV (Chrome-Moly-Vanadium) 4150 barrels provides excellent coating uniformity and no tolerance build up in the barrel to create deviation. Our melonited barrels have higher lubricity, last longer and are just plain tougher than chrome lining. The barrel chambers are speed polished, reducing resistance on the cartridge entering and exiting the chamber.
