E&C Sig Sauer MCX Virtus AEG - Grey

SIG MCX Virtus AEG by E&C

The SIG MCX Virtus by E&C is a precise full-metal replica of the iconic assault rifle, trusted by elite units around the world. The real firearm was introduced in 2015 and now forms the basis of the new U.S. Army service rifle (SIG MCX-SPEAR). This airsoft version features a true 1:1 scale and detailed workmanship. The handguard is CNC-machined and includes M-LOK slots at 3, 6, and 9 o’clock positions for tactical attachments. The top RIS rail allows mounting of any optics or red dot sight. The gun includes a functional bolt catch, ambidextrous fire selector, and a modern PDW-style adjustable stock with 3 positions. Its construction is designed with easy servicing in mind and is inspired by the real weapon.
At the heart of the gun is a standard V2 QSC gearbox with quick spring change, which allows power tuning without removing the gearbox from the body. The battery is installed in the handguard; since the space is very tight, a suitable battery would be a 7.4V Li-Po Stick or Nunchuk, installed around the outer barrel inside the handguard. For full performance, an 11.1V Li-Po/Li-Ion battery is recommended, but it must be stored externally in a battery box or after modifying the handguard. The E-shooter Kestrel Basic ETU V2 unit improves trigger response, protects electronics, and allows basic programming.
