The SR-16 model of rifle was developed by Knight’s Armament Company in the early 2000’s as an improvement upon the tried and true AR15 platform. With notable features like select-fire and true ambidextrous capability, it helped to further establish KAC as a world-renowned firearms manufacturer. Fast-forward almost 20 years later, we now have the SR-16E Mod2, an even further improved version of this excellent rifle.
The Evike Manufacturing Group saw it fit to make the Licensed Knight’s Armament Co SR-16E Mod2 the very first release from the Helios brand, a high-end line of Airsoft rifles offered at an entry-level price.
The Helios KAC SR-16 Mod2 faithfully recreates the details of the real rifle. This AEG features high-detail KAC trademarks on both side of the receiver, giving it an authentic appearance. The rifle features a licensed URX4 MLOK handgaurd at the front, prefect for mounting all kinds of MLOK accessories. On top you’ll find a full-length 20mm Picatinny rail for optics, with high-quality polymer KAC Micro front and rear folding sights. The ambidextrous selector, bolt-catch, and magazine release have all been included on this rifle making it a great platform for all users.
Internally the Helios SR-16E Mod2 features an ARES EFCS Version 2 gearbox, providing excellent performance right out of the box. The EFCS features a QD spring, crisp electronic trigger, and the potential for user adjustability with ARES’ optional EFCS programming box (sold separately). Beyond the gearbox, the Helios SR-16E Mod2 AEG features a rotary hopup unit mated to a tightbore aluminum inner barrel, for precise adjustment and consistent accuracy.
