All rights to this unique content are bound to the anareus.cz domain.Colt x Cybergun M4A1 CQBR 10.5" Gen2 (SA-E03 EDGE™) by Specna Arms combines the classic appearance of the legendary M4A1 with modern EDGE™ Gen.2 internals. The full-metal receiver with durable Nano Coating finish features licensed COLT and M4A1 markings along with the Rampant Colt logo. The front RIS handguard allows you to mount foregrips, weapon lights, laser modules and other accessories, while the removable carry handle retains the classic military appearance and, once removed, exposes the top RIS rail for a red dot sight or rifle scope. At the heart of the rifle is a reinforced Æther™ V2 gearbox with 8 mm bearings, steel gears, a piston with a full-metal rack and high-quality compression components. The HAL² ETU™ electronic unit uses the Hall effect for extremely precise trigger detection across up to 500 positions and, thanks to Bluetooth, can be configured through the Specna Link™ mobile app. Players can adjust trigger sensitivity, pre-cocking, SEMI, BINARY, BURST and AUTO modes, burst length or RoF and monitor the status of the rifle and battery. Accuracy is provided by the rotary TDC Magnus hop-up unit, Helium™ Flat Hop bucking and precision 6.03 mm inner barrel. The ESA™ system also allows quick replacement of the main spring without disassembling the gearbox. The result is a modern AEG that retains the authentic appearance of a service M4A1 while offering the features of today's electronically controlled airsoft rifles.
