The Huldra Mark IV patented piston technology will run cleaner, cooler and longer than any other AR. The piston system parts and barrel have been treated with a salt nitride Meloniting process, making them harder than hard chrome. The Melonited process gives the barrel higher lubricity, longer life and a uniform coating and resistance to build-up. The upper and lower receivers are machined from high-quality aluminum forgings, with critical tooling dimensions held within +/- .001 inch. The mil-spec buffer tube is precision machined from high-quality aluminum as well. The magwell front features recessed chevrons for improved control. The Mark IV is simple perfection in a semi-automatic firearm.
