The KAC SR-16E Mod2 by ARES / EMG is a licensed replica of the modern Knight's Armament rifle, combining realistic styling, low weight, and advanced electronics. The rifle features a fiber-reinforced polymer receiver that offers excellent durability while remaining lightweight for all-day use. Inside, you'll find the ARES EFCS V2 gearbox with an electronic trigger system that provides fast trigger response and crisp operation without unnecessary delay. Thanks to the QSC (Quick Spring Change) system, spring changes can be performed quickly without disassembling the rifle. Accuracy is supported by a rotary hop-up chamber and a 6.03 mm precision inner barrel. The URX4 M-LOK handguard allows easy accessory mounting, while the full-length top RIS rail is ready for a optic. The rifle also features fully ambidextrous controls, making it equally comfortable for both right-handed and left-handed shooters.
We recommend a 7.4V Li-Pol buffer stick battery with a T-Dean connector. 11.1V batteries can also be used, but the EFCS unit may be factory-programmed for 7.4V operation and the rifle may not fire until reprogrammed (ARES EFCS programming device is not included).
Yes. Thanks to the electronic trigger system and factory tuning, it is ready for use straight out of the box.
Yes. The QSC system allows quick spring changes through the buffer tube, making it easy to adjust power levels to meet field requirements.
