Designed, manufactured, and inspected to Airborne Arms' demanding standards, the Hyperion series of barrels deliver the accuracy, reliability, and extended barrel life demanded by today's high end shooters. Each Airborne Arms Hyperion Series barrel is turned from button rifled 416R stainless steel and features a 5/8-24 thread pitch with an 11 degree crown for enhanced accuracy. Once manufacturing is complete, they hand polish the M4 feed ramps and inspect each barrel before carefully packing them in a "Floating Triangle" packaging to ensure that they arrive in the same condition they left in.
