Available exclusively on Beatport March 23rd, the final chapter in the AR-120 series of assault gear comes from none other than Double Helix. His sound is as unmistakable as a Kalashnikov, and his tracks have seen the same kind of wide-spread use and environmental adaptability as well. Upon looking at the Engine EP's configuration, however, any fool can see it's not your standard AK-47. Double Helix's AR-129 Engine EP is a gas piston operated action, selective fire assault rifle in the gloriously balanced and maneuverable ambidextrous bullpup configuration. It comes standard with a 3-stage progressive trigger, allowing for quick single shot, 3 round burst or full auto selection, and integrated telescopic sight. Engine is the standard variant, featuring additional modification to the bolt carrier group, striker, and trigger mechanism and fires from an open bolt. It features rail systems on the 4x integrated sight and an extended 42 round magazine. At 174 RPM, it will keep any floor dancing on full auto. The Deep Down variant, intended for special forces and close quarters use, fires from a closed bolt and features rail systems along the optics and both sides of the barrel. It comes stock with the translucent, double-column 30 round box mag, and the integrated 1.5x-3x telescopic sight features thermal optics. Designed with low-light roof-top line-drops in mind, Deep Down is succinct, precise, and quick while still being dynamic and moodish and thusly prepared for any situation.
