The most prominent change is the addition of the Eshooter Kestrel Basic ETU, offering plenty of slick functionality previously reserved for far more expensive, high end replicas.

    The Kestrel Basic offers programmable fire modes including 3-round burst and binary trigger, adjustable pre-cocking, active braking, cycle completion, low battery warning and low/high voltage protection. The Kestrel keeps your gearbox cycling at maximum efficiency and with pre-cocking set, provides an incredibly snappy trigger response ideally suited to rapid double taps. Also inside is a 6.03mm tightbore inner barrel and rotary HOP-up unit, bringing the latest iteration of the ONE™ series into line with EDGE™ and EDGE 2.0™ platforms with improved accuracy potential and the latest HOP-up unit design for M4 AEGs.

    If you love an AR that stands out, rocking a customised look straight out of the box, the SA-V26 ONE™ Red Edition M4/AR-15 LVOA AEG; Kestrel Basic ETU is exactly that. An impressive reinvention of a popular previous release with the latest tech inside, this is the AR platform for skirmishers with a sense of style!
