Huldra's 5.56 x 45 Upper is a standard mil-spec part that will work on any mil-spec AR lower. The mid-length piston system will give the benefits of a longer forearm by having a more ergonomic grip and longer sight radius for quicker acquisition and less felt recoil. The Huldra patented piston system runs cleaner, cooler and longer than any other AR. The piston parts and barrel are treated with the 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.
